Marsha de Cordova - the MP for Battersea - gets things going south of the river.

She says Battersea has a "proud and radical history", pointing out that in 1913, John Archer was selected as Mayor of Battersea - the first black mayor in London.

But now, Ms de Cordova says, London is facing huge challenges, including a rise in foodbank use and ill effects of the "Tory Brexit chaos".

Boris Johnson is also hitting the campaign trail ahead of December's election.

The Labour shadow cabinet are now on stage, and they've been applauded for about three or four minutes non-stop while we wait for Mr Corbyn.

It's filling up at Battersea Arts Centre in south London ahead of Labour's campaign launch.

Jeremy Corbyn is due to speak shortly and BBC assistant political editor Norman Smith is on site to cover the event.

The building was gutted by a huge fire in 2015 but has since been restored.

Faiza Shaheen, who is standing for election for Labour in Chingford and Woodford Green, says this “is a critical time in history” and that’s why she is “not going to shut up”.

She says she has already been on the receiving end of Islamophobic abuse.

“People will abuse us - and it’s not OK and I will fight that - but I’m not going to give up because of that,” she says.

Dr Anwara Ali, who is the Conservative candidate in the seat of Harrow West, says she wants to stand because she believes Parliament should have more female representatives and people from ethnic minorities.

She says: “I think it's really important that our Parliament represents the diverse communities that live in this country - at the moment it's not representative and therefore our democracy is weaker because of that.”

She adds: “I've also faced social media abuse on Twitter and so forth but running away from it is not going to solve the problem. We need to face it.”

Chloe Hutchinson, the Lib Dem candidate for Swansea East, says she’s standing because she thinks “Brexit is a mess” and she strongly believes that the UK is better off in the European Union.

She says she has a really supportive team which won’t stop her from getting abuse but that support is “something that all candidates need”.

More than 300,000 people have applied to register to vote in 48 hours, according to government figures.

A total of 139,162 applications were submitted on Tuesday, followed by 177,105 on Wednesday.

They are the highest and second highest number of applications submitted on a single day this year.

Nearly two-thirds (65%) of applications were from people aged 34 and under, while just 4% came from those aged 65 and over.

A third were from people under 25.

The increase in the volume of applications should not be treated as direct evidence of an increase in the number of people able to vote.

At previous elections there have been applications from people below the legal age to vote or who are already on the electoral register.

You can register here, external - the deadline for applying is Tuesday 26 November.

Facebook chief executive Mark Zuckerberg has stood by his company's decision to run political adverts after Twitter announced it would ban them.

Facebook has faced criticism after disclosing it would not fact-check most political ads, instead only banning adverts containing claims debunked by third-party fact-checkers.

Less than an hour after Twitter's announcement, Mr Zuckerberg spoke about what he said was Facebook's deep belief "that political speech is important" and stood by his company's decision.

"Some people accuse us of allowing speech because they think all we care about is making money, and that's wrong," he said in a Facebook earnings conference call.

"I can assure you that, from a business perspective, the controversy this creates far outweighs the very small percentage of our business that these political ads make up.

"I don't think anyone can say that we are not doing what we believe or we haven't thought hard about these issues."

Thermals advised, particularly during December campaigning in Scotland.

As the country prepares for a 12 December election, readers have been sending in questions.

Here are a selection of those questions - and the answers.

One digital media expert isn't so sure...

...and Damian Collins, the chair of the Digital, Culture, Media and Sport select committee, also feels Twitter has missed the mark:

Labour MP Ian Lucas, who is standing down at the election for family reasons, says social media has resulted in a political debate "dominated by the extremes".

The MP for Wrexham announced he was stepping down just weeks after a man with a "vendetta" against the MP was jailed for 16 months for abusing his wife and public relations officer.

He told 5 Live: "I’ve been an MP for 18 years, it’s only in the last four or five years that any of these incidents have happened. We used to have an open-door policy which did not cause a difficulty."

He said social media was partly to blame as it wasn't a sensible forum for debate, adding “we have an incredibly polarised debate which is dominated by the extremes”.

Mims Davies - the Tory MP for Eastleigh who is stepping down at the election - has told 5 Live the upcoming election could go one of two ways.

“This could be the most miserable and divisive and horrible election going, off the back of three-and-a-half difficult years following the referendum result," she said.

"Or, this is a chance for new political leadership, new MPs, people coming forward with the next stage of ideas to throw that off and use this as an opportunity to move this country forward, to move political debate forward and find the positives which we have in this country."

A Guardian political correspondent spots an advertising van for the Liberal Democrats in Westminster:

A senior rabbi has written to his congregation urging them to vote tactically against the Labour party, reports the Jewish Chronicle.

Rabbi Dr Jonathan Romain is said to have written to 823 families to say a Jeremy Corbyn government would be a "danger to Jewish life as we know it".

According to the Chronicle, Dr Romain wrote: “I should stress that the problem is not the Labour Party itself, which has a long record of fighting discrimination and prejudice, but the problem is Jeremy Corbyn. Corbyn-led Labour, has at best, let anti-Semitism arise within its ranks, or at worst, has encouraged it."

It's early days in the campaign but political advertising on social media has already begun:

A number of MPs are making the point on social media that the prime minister promised "do or die" that the UK would leave the EU today.

Transport Secretary Grant Shapps says "the idea that all the moderates are going" from the Conservative Party is "complete nonsense".

The Tory MP was asked about his reaction to female MPs, including Amber Rudd and Nicky Morgan, standing down.

He replies that "it's not unusual" for people to stand down for all sorts of reasons before the election.

He adds: "I'm a Remain voter, in cabinet I sit next to the housing secretary who is a Remain voter and next to the chief secretary of the Treasury who is also a Remainer and so on.

"There are lots of Remainers who are lots of moderate, reasonable people who think it is right to observe what the electorate said when they voted in that referendum and, since we have a deal, to actually pass it."

Thousands of people are tweeting the hashtag #BrexitDay - as today was the deadline for the UK leaving the EU.

Boris Johnson had pledged to take Britain out by today "do or die" but was forced to seek an extension which the EU granted.

Many of the tweets come from Remain-supporters cracking jokes while in others, Brexiteers are blaming politicians and expressing disappointment it has not happened yet.

Among those who tweeted was the Scottish writer Irvine Welsh, and a local councillor in Epping Forest, Holly Whitbread.
