MPs are expected to start debating a bill to call an early general election in about 10 minutes.

It's only lunchtime, but a lot has happened already. Here's your handy recap:

• Labour has signalled its intention to back the bill, meaning an election in December now looks likely.
• Mr Corbyn said Labour would launch "the most ambitious and radical campaign... our country has ever seen."
• But there has been dissent from some Labour MPs who said they would vote against an early election - Peter Kyle MP said it "won't solve the Brexit challenge".

• The bill proposes an election date of 12 December, but the SNP and Lib Dems want a 9 December poll, saying the earlier date would prevent the prime minister from pushing his Brexit deal through Parliament.
• No 10 sources have told the BBC they would accept 11 December to get opposition parties on-board. Watch out for how this pans out.
• Because it's a bill, amendments can be tabled which MPs can vote on - potentially changing the final bill significantly. The amendments haven't been announced yet but keep an eye out for ones on changing the date; allowing 16 and 17-year-olds to vote; and giving EU nationals a vote.
• Though the prime minister's spokesman isn't keen on changing the franchise this close to (a potential) polling day.

Education secretary Gavin Williamson said it was "welcome" to hear the Labour party would support an early general election, adding "let's see if they deliver on their word".

Speaking on a visit to Stamford Bridge, he said parliament was "rotten" and standing in the way of delivering Brexit.

“You can’t have Labour blocking a no deal, blocking a deal and then blocking an election, so let’s see if they deliver on their word.”

“Parliament is rotten, it is broken... we need to go to the people and let them have a choice.”

While all talk is focused on a possible December election, staff at the People's Vote campaign for another EU referendum have been locked in an extraordinary public stand-off with the group's chairman, Roland Rudd.

Mr Rudd - the brother of former Tory cabinet minister Amber Rudd - was supposed to meet staff at the campaign's Millbank Tower office at 10:00 GMT to talk about the row over his attempt to sack the campaign's director and head of communications.

Posting from the official People's Vote twitter account, staff say Mr Rudd is refusing to meet them as planned and is pushing to move the meeting to a hotel, but staff want to stay in the office.

The spat comes after Mr Rudd emailed staff on Sunday evening announcing that James McGrory, the campaign director, and Tom Baldwin, the head of communications, had been dismissed.

Staff wrote a strongly-worded letter replying to Mr Rudd, voicing their support for Mr McGrory and Mr Baldwin.

Mr Rudd denied on Monday there was any row, telling BBC Radio 4's Today programme: "I want to make clear, there's no row about the remain side and PV. Everyone knows where we stand on this."

The prime minister's spokesman says changing the election franchise days before an election could cause "administrative chaos".

"There would be between 2.4 million to three million people added to the electoral roll at the last minute with no idea on the cost or logistical burden this could cause," he said.

"This may, in turn, lead to delays with polling cards, postal votes and at polling stations that could undermine everyone's ability to vote in the election.

"It would also mean EU nationals in the UK enjoying wider voting rights than UK nationals in any other country other than Ireland."

While there's talk of an amendment to allow 16 and 17-year-olds to vote in a December election, at the moment you have to be 18 to vote.

The prime minister's official spokesman says it would be "administratively impossible" for the general election bill to be amended to allow votes for 16 and 17-year-olds.

"The government's position has not changed: we have no plans to lower the national voting age," he says.

"Eighteen is widely recognised as the age people become an adult. Below the age of 18 you are treated as a minor in both the foster care system and the criminal justice system.

"Full citizenship rights including voting should be gained at adulthood."

Labour MP Barry Sheerman claims Jeremy Corbyn was persuaded to back an election by two of his closest aides, Seumas Milne and Karie Murphy, despite "a clear majority" of the shadow cabinet being against the idea.

BBC news correspondent Jon Kay says he will not be approaching Brenda from Bristol for comment on a possible December election.

Downing Street says the government is prepared to look at amendments to change the date of its proposed election to one which is "logistically possible".

The prime minister's official spokesman says a poll on 9 December would not be logistically possible, but that 10 and 11 December would be considered by the government.

Ruth Davidson, the former leader of the Conservatives in Scotland, insists her party does not face being wiped out by a general election.

Ms Davidson - who stood down in the summer so she could spend more time with her family - says she thinks the Tories will do well and says she will do everything she can to support the campaign.

Former Conservative MP Heidi Allen - who was briefly leader of Change UK before joining the Liberal Democrats earlier this month - has announced she will step down from her seat in the next general election.

Writing to her constituents, Ms Allen said she was "exhausted by the invasion into my privacy and the nastiness and intimidation that has become commonplace".

The MP for South Cambridgeshire added Brexit had "broken our politics" and only a new referendum could solve the deadlock.

Former Tory leadership candidate Sam Gyimah has revealed he will stand for the Liberal Democrats in Kensington, a key battleground for Labour and the Conservatives.

The ex-Tory MP says he will quit his East Surrey constituency for Kensington, where the Lib Dems took 4,724 votes in 2017 compared to 16,000 each for Labour and the Tories.

He told the Evening Standard, external: "I want to roll my sleeves up and fight on issues and values that I stand for — openness, inclusivity and the fundamentals of liberal democracy that I know a majority in Kensington aspire to."

Alastair Campbell - who was campaign director for former PM Tony Blair - believes Labour is making a mistake in supporting a general election.

Mr Campbell argues there should instead by a new referendum, something he has repeatedly campaigned for.

"It's about time," says vice chairman of the Conservative Party Paul Scully about a general election.

"We need to get rid of this dead Parliament and unlock Brexit," he says.

Asked about offering votes for 16 and 17-year olds, he says "it is just not the right time to change the whole franchise".

UK elections usually take place in May or June - the last December election was in 1923 - so what difference might a winter election make?

Will - for example - bad weather stop people voting?

This is an enduring idea that instinctively feels right. In the cold and damp December weather, surely people will be less inclined to turn out and vote.

However, experts say there is no evidence from the UK to suggest that bad weather stops people from voting.

Research from the University of Oxford found virtually no correlation between the weather and turnout - instead people are more likely to vote if the election race is close and there is a strong difference between the leading parties.
