if Andy Burnham is chosen as the Labour Party's candidate for the Makerfield by-election, he faces a significant challenge at the hands of Reform UK, which made gains in the area during the local elections last week.

Makerfield is a parliamentary constituency, which has different boundary lines to a local authority, so can make comparing local and general election results a little bit tricky.

Eight core council wards sit almost entirely inside the Makerfield constituency boundary line, and these are overseen by Wigan Council. There are other wards that partly cross into the Makerfield area, but not substantially.

All of these eight core wards declared for Reform UK last Thursday. In the previous local elections in the area held in 2024, seven of them had declared for Labour while one ward had declared independent.

This means that Reform took seven councillors from Labour in the Makerfield area.

It's a trend reflected in the wider Wigan area, with Reform gaining 24 councillors and Labour losing 22. However, as only a third of council seats were up for grabs in Wigan last week, it didn't change the council's overall control - it is still Labour-held.

A lot of hurdles to Andy Burnham's return to Westminster have been cleared, but there are more to come.

Monday is the deadline for any other candidates to put themselves forward to stand for Labour in Makerfield.

If others do, then a decision on the chosen Labour candidate will be made on Thursday.

Then the biggest hurdle of all: can Burnham win the seat?

Makerfield used to be quite a safe seat, but Reform decimated Labour at last week's local elections.

They won half the vote compared to Labour winning less than a quarter.

This is a big challenge for Burnham. If Reform win that will be a major achievement for Nigel Farage's party on their campaign for Downing Street.

Many in the Labour Party are seeing this as a proof of concept. If Burnham can beat Reform UK in Makerfield, then the argument goes that he is the best person to take on Reform across the country in the build up to the next General Election.

Not for the first time we are in for a roller coaster few weeks in British politics.

Andy Burnham is seeking a return to Parliament. Wes Streeting has resigned as health secretary after losing confidence in the PM. Dozens of Labour MPs have called on Starmer to step down.

However, there has been no leadership contest triggered - yet.

So, what are the five possible scenarios we could see play out in the coming weeks?

1. Starmer decides to stands down: The prime minister might simply decide he's had enough, but this option seems unlikely after repeatedly stating he would not "walk away" and would fight any challenge
2. There is a leadership contest, without Burnham: Any Labour MP could trigger a leadership contest with the backing of 81 of the party's MPs. It was thought that Streeting could be the one to do this, until he declared in his resignation letter this week that he wanted a "debate about what comes next"
3. Burnham wins the by-election and fights Starmer for leadership: This scenario involves a leap of imagination in which Burnham is selected for, and wins, Makerfield and then receives the backing to challenge the PM once in Parliament. If such circumstances come to pass, it could set Burnham on a course to No 10
4. Burnham wins by-election and Starmer steps down: However, a Burnham Makerfield victory would send a clear signal to the PM, who may choose to leave office rather than contest a one-on-one race with Burnham
5. Burnham loses by-election and all bets are off: There's every chance that Burnham could lose the Makerfield by-election. If this occurs, all bets are off and the paralysis at the top of the Labour Party would enter a new and uncertain phase - while eyes turn to other Labour MPs to see if another challenge would be mounted

How much could the Makerfield by-election, and possible Manchester mayoral election, cost?published at 07:47 BST

When Labour’s National Executive Committee blocked Andy Burnham from standing in the Gorton and Denton by-election in January, one of the reasons it gave was the cost of holding an election for a new Greater Manchester mayor if he became an MP.

If Burnham is selected as a candidate for the Makerfield by-election, the rules would allow him to stand in a Parliamentary election while still being mayor, but if he won then he would have to resign his mayoralty.

The Greater Manchester Combined Authority (GMCA) told BBC Verify that the 2024 mayoral election cost it £4,719,754. The GMCA’s funding includes grants from central government and money raised from taxpayers locally.

In addition, there is also the cost of the Makerfield by-election after Josh Simons announced he is standing down to make way for Burnham.

The maximum cost that returning officers can claim back for Parliamentary elections is set out in legislation that specifies it for each constituency, external.

The figure for Makerfield is £226,208.

Labour MP for Makerfield Josh Simons announced on Thursday he would resign to pave the way for Greater Manchester Mayor Andy Burnham to run for a seat in the Commons.

Simons won the Greater Manchester seat in the 2024 election. It was his first tilt for Parliament.

The constituency boundaries were changed slightly in that election, but the seat has been Labour-held for decades.

In the 2024 election, Simons won with 18,202 votes - 45.2% - with Reform UK coming second with 12,803 votes, 31.8% of the vote.

A Labour MP has described how Andy Burnham has been a "nightmare for the Labour Party" and that he does not think "he can ride to the rescue".

Neil Coyle tells BBC Newsnight that Burnham has been a good mayor of Manchester but he has been saying he wants to take over since Keir Starmer won a massive majority.

"Frankly, some of us are sick of it," he says.

He adds: "I've had dozens of ... members of the public emailing, phoning, texting, stopping me in the street to say, what on earth is he thinking of? This is so unhelpful."

Coyle also says organising the by-election could have a "huge cost to Manchester with no guarantees that Labour will win in that seat".

"It is a terrible scenario, entirely self-inflicted, and the NEC (National Executive Committee) should be stronger at standing up to the egos of one man," he adds.

Greater Manchester Mayor Andy Burnham is one step closer to returning to Westminster, having been cleared by Labour's ruling body to run for selection in the Makerfield by-election.

Josh Simons announced he would resign as MP for Makerfield, paving the way for a potential return for Burnham. The mayor is widely expected to try and challenge Prime Minister Keir Starmer as Labour Party leader.

The BBC understands the by-election is likely to take place on 18 June.

Talk of a leadership contest has dominated Westminster following bruising election results for the Labour Party last week.

Its deputy leader Lucy Powell said on Friday that Burnham was needed as a "key player" in Westminster.

Burnham's leadership ambitions are no secret - but there are several hurdles he needs to overcome if he wants to ultimately challenge the PM.

First, he needs to be selected as the local party's candidate. Then he faces the challenge of winning the by-election.

If he wins, Burnham will then need to secure the backing of 81 Labour MPs if he wants to launch a leadership challenge against Starmer.

Meanwhile, Wes Streeting - who resigned as health secretary on Wednesday saying he had "lost confidence" in the PM - has enough support to trigger a race, allies say.

It's also widely believed that former deputy PM Angela Rayner may also throw her hat in the ring, having now resolved her tax affairs with HMRC.
