Earlier this week I wrote a story that Jeremy Corbyn’s office was supporting Sam Wheeler, the high profile Momentum activist, to replace Sir Gerald Kaufman in Manchester Gorton. Paul Waugh at the Huffington Post reported a similar story. 

Following my exclusive article earlier today about Manchester Councillor Kate Chappell triggering a by-election, she has been in touch to confirm the story. 

She has denied accusations made to me by over a dozen Manchester political figures that she had been bullied.

Here is her full statement:

It is my intention to resign from Manchester City Council but it is not at all true that I've been bullied by members of Rusholme branch or that I feared deselection. The people who said that to you are mistaken.

Multiple sources have told me that Rusholme ward Councillor Kate Chappell, who is currently on maternity leave from Manchester City Council, will be resigning and triggering a by-election for May. 

Here is a piece on runners and riders in Manchester Gorton for the Labour Party selection. There are around 2,000 members eligible to vote. If you know someone running message me at mike@writeyou.london. There are numerous other Gorton articles that can be viewed on the main page of the site.

*Breaking* After this article was published we received reports that Afzal Khan's Manchester office has been bricked by masked youths. 

Today the battle for Manchester Gorton intensified following the sad passing of Sir Gerald Kaufman on Sunday.

My understanding from senior sources is that there are moves for the seat to be a woman, if as expected the by-election is on the same day as the local elections. A senior union source told me, “it would be ******* mad” for the candidate to be a white man, given that Andy Burnham is also a white man. Another local Labour source told, "This selection is an opportunity to ensure Manchester Parliamentarians are as diverse as the city they represent".

A few weeks ago I wrote a detailed article about the shadow campaign in Manchester Gorton. 

Following the very sad passing of Sir Gerald Kaufman multiple sources have told me that Councillor Mike Amesbury, Afzal Khan MEP, Councillor Julie Reid and Momentum activist Sam Wheeler are making moves to stand already. Wheeler is being aggressively supported by Jeremy Corbyn’s office. It’s likely that Councillor Rabnawaz Akbar and Councillor Luthfur Rahman will also stand. The selection is likely to be bitter and acrimonious, judging by the text messages I’ve already received about rival candidates. Campaigning started earlier this morning and all sides are engaging in aggressive manoeuvring. 

At this stage Khan must be seen as the front runner. The New Statesman reported earlier that Khan and Reid were potential candidates. The Huffington Post has reported that Sam Wheeler is being supported by people close to Jeremy Corbyn.

We've put together a magazine of WriteYou 2016 showcasing some of our best articles. Please read and download below. 

I am running a live blog of events in Stoke and Copeland By-Elections, reporting on events on the Labour campaign (this live blog is not in support of the Labour Party, WriteYou is a non-partisan site). If you enjoy this coverage please click here to help fundraise to take the site to the next level. 

03:00 - Labour lose Copeland. And the results show clearly that UKIP voters trended Tory and Labour voters trended Lib Dems. This is a deep question that Labour has to answer in order to win. More on this tomorrow.

02:30 - Labour win Stoke. As Adam Bienkov points out this result is further evidence that Lib Dems & Tories are a bigger threat to Labour than UKIP. 

John Curtice — Labour have seriously misread their Brexit problem. Most of the votes they've lost since referendum have been to Lib Dems.

— Adam Bienkov (@AdamBienkov) February 24, 2017

01:49 - Labour's Pollster Michael Turner of BMG Research trolling Arron Banks over Stoke Central:

#superforecasting from @Arron_banks and @LeaveEUOfficial #stokebyelection https://t.co/IaBzyRgzbA

— Michael Turner (@pollstermike) February 24, 2017

01:12 - Looks like Labour will win by 3,000 at least in Stoke and lose to the Tories by at least 1,000 in Copeland.

00:33 Labour's ground game shouldn't be underestimated in low turnout elections. 

Testament to an excellent ground campaign today in spite of Storm Doris 👍🏻 https://t.co/OAA6rsRMR0

— Wes Streeting MP (@wesstreeting) February 24, 2017

00:23 Turnout in Copeland 51.35% much higher than expected. This means PVs are roughly the same as 2015, meaning that Labour didn't manage to get more than 2015 onto PVs. The question then is who turned out to vote. 

00:16 Turnout of 38.16% in Stoke would indicate the information we reported earlier that Labour sources were predicting as much as a 3-5,000 victory could be correct. Labour's formidable ground game at work here. 

00:02 - Sky News are reporting that there are 9,000 postal votes. In 2015 there were 9737 on a 63.8% turnout. As turnout is expected to be at least 20% less than 2015, they will take a significant role in final result. 

11:54 - Dan Hodges reporting Tories ahead. 

Source at the Copeland count says Tories edging ahead now.

— (((Dan Hodges))) (@DPJHodges) February 23, 2017

11:41pm - Lots of different theories going around. Labour commentator Dan Hodges: 

Labour source re-Copeland: "Early samples look like we will win".

— (((Dan Hodges))) (@DPJHodges) February 23, 2017

Libs Dems say their numbers suggest a Tory win here in Copeland. Even on the night, but Tories beating Labour on postal votes to snatch it.

— Daniel Hewitt (@DanielHewittITV) February 23, 2017 

I think part of the problem tonight is you've got about half a different types of expectation management going on. Especially on Lab side.

— (((Dan Hodges))) (@DPJHodges) February 23, 2017

Hold the mayo. Source at the Copeland count now tells me Tory boxes held up by closure of A66. Now neck and neck.

— (((Dan Hodges))) (@DPJHodges) February 23, 2017

10:29pm - Labour source gets in touch to provide Jeremy Corbyn's email to PLP at close of polls:

10:25pm - We started reporting yesterday, that Labour expected to lose in Copeland. Some Labour sources still think Labour can win, but I'm not so sure. 

Tories 'very bullish' about their prospects in Copeland, says @JoshHalliday - https://t.co/VakvEkSoIq

— AndrewSparrow (@AndrewSparrow) February 23, 2017

10:21pm - the counting has begun

First ballot box has arrived in #Copeland. Now the long count begins. pic.twitter.com/RGIBZOXfGL

— Paul Brand (@PaulBrandITV) February 23, 2017

10:00pm - Several Labour sources on the ground have predicted that Labour will by as much as 5,000 with Tories in second and UKIP in third. Copeland probable Labour loss but very close. 

9:23pm - not long left now. Copeland could go either way at this point but provided there isn't a total shock Labour will win Stoke. 

8:40pm - Labour sources on the ground in Copeland think that is very close and difficult to call. In Stoke, it seems the Labour GOTV campaign is managing to persuade people how to vote. Local sources say that there are reports across the constituency of Labour's on the ground operation being effective.  

7:06pm -  Tory source backing up our turnout report and my below reporting about UKIP voters going Tory. 

Sources on the ground in Stoke say Tories siphoning off UKIP Pledges.
Turnout will be low. #stokebyelection

— Callum Wright (@LewisCallum) February 23, 2017

6:50pm- Following our exclusive report that Labour's Elections Director is confident that Labour will win Stoke, I've heard from a well respected elections veteran on the ground who says "it is in the bag".

6:10pm - I have a brief update on the Labour Party campaign. My understanding from very senior sources is that Labour HQ is doing advanced digital advertising in both by-elections. This team that sits under Patrick Heneghan, the Executive Director of Elections, and is run by Tom Lavelle are targeting voters based on their voting intention and propensity to vote. They are doing this through the purchase of external data and Facebook advertising. Tom's team is a relatively new operation that was started after the 2016 elections. My understanding from sources close to the Labour Leader is that Patrick is confident Labour will win stoke, but thinks that Copeland is on a knife edge. 

5:19pm - Sources in stoke say that turnout is very slow. I've been told that activists are walking around for hours and hardly getting anyone in. This is to some extent normal, but I'm told this is worse than usual. There are increasing fears in the Labour camp of a low turnout. (For avoidance of doubt following Twitter comments, this isn't about Labour's election chances, but about turnout)

4:45pm - just a quick update on the Labour campaign in Copeland and Stoke. The Copeland campaign is being run by the Regional Director of Labour North, the formidable and highly respected Fiona Stanton. The MP in charge is Andrew Gwynne. Stanton is a veteran of running by-election campaigns and from personal experience will be running a ruthlessly organised campaign up there. Stoke is being run by the newly appointed West Midlands Regional Director George Sinnott. The MP is Jack Dromey. 

4:28pm - the wildcard in Copeland is of course the number of postal votes. In 2015 there were 12,218 postal votes in Copeland or 19.4%. 9737 were returned or 24.5% of the overall vote. This will almost certainly be higher this time due to the Labour Party's famed postal vote operation. I've just been told that the weather is absolutely shocking and likely to depress turnout. In this instance, postal votes will take on a far more significant angle. I am trying to find out info about PVs and will write about this if I find out any more info.

I'm also told that Whitehaven is a lot better for Labour than Keswick. This again brings differential turnout to the fore. 

I'm told activist turnout in Stoke is huge and Labour HQ sent a coach of non-essential staffers to Stoke. 

3:50pm update - Some Labour sources in Copeland tell me that they personally think that the election is very close and closer than some people expect because of the local NHS issue, as I explained yesterday. These sources think the race will come down to differential turnout, i.e what type of voter turns out. The electoral maths make the seat very tight. In the 2015 Parliament the average reduction in turnout is about 20%. So turnout in 2015 in Copeland was 63.8. So if we budget for a 43.8% turnout this would mean there would be roughly 27,345 voters. Based on the 2015 figures the result would be if exactly the same:

Labour 11,566 - Tory 9,789 - UKIP 4,238 - Lib Dems 957 - Greens 820

I'm told by 2 members of the Shadow Cabinet and multiple people knocking on doors, that our vote isn't holding up. I'm also told that the Tories are heavily working the seat and the Lib Dems are trying to aggressively mop up Labour voters annoyed with Labour over brexit. The national polls show that UKIP voters are trending Tory and Labour voters are trending Lib Dem. This makes the seat very close but at this point, looks like Labour will lose.

I also understand from people knocking on doors that Labour are using targeting technology to add likely Labour voters to their door knocking sheets. This means that they haven't identified enough promises, to make the people in Labour's Southside HQ completely comfortable. 

Sources on the ground in Stoke, tell me things are going as expected and it is likely Labour will win there.
