It's the day the UK was due to leave the European Union. But, when Jeremy Corbyn talks of a "once-in-a-generation chance to transform our country" later, it will be a general election - rather than Brexit - on his mind.

He will launch Labour's campaign ahead of the 12 December poll with a pitch to "rebuild" public services and tackle "tax dodgers, dodgy landlords, bad bosses and big polluters".

Boris Johnson, who wanted Brexit to happen today, blames his Labour rival for the delay.

In campaign visits later, the prime minister is expected to focus on Brexit, before moving on to domestic priorities concerning schools, hospitals and crime. Liberal Democrat leader Jo Swinson, meanwhile, is campaigning as a "candidate to be prime minister".

Our round-up offers a taste of the UK parties' social media campaigning - free and paid for - in the 24 hours after the Commons agreed the election date.

Has Banksy been photographed at work?

A book is claiming to show the famously elusive artist Banksy creating works at various locations. Its author and photographer Steve Lazarides certainly ought to have had the necessary access to the Bristol graffiti art pioneer. He worked with him for "11 glorious years", including as his agent, driver and gallerist. Our report features some of Lazarides' photos from Banksy - Captured. There is a catch, though. None of them show the subject's face.

How to have an offence-free Halloween

By BBC Newsbeat

Gone are the days of dressing as a witch or pumpkin, now it's all about showing off how savvy your pop-culture knowledge is. But we're also living in a time where outrage is only a click away, and the potential for outfits to offend is higher than ever.

What the papers say

For several papers, the general election is already the main story. The Times describes an "exodus of moderate Tory MPs" ahead of the December 12 poll, although the Daily Telegraph says the Conservatives could be boosted by the Brexit Party withdrawing candidates. The Daily Mail has polling suggesting Boris Johnson is more trusted on the NHS than his Labour rival Jeremy Corbyn, even as the Daily Mirror says the Conservative leader will open the health service to US "profiteers" in a "desperate scramble" for a trade deal. Others focus on the report into the Grenfell Tower fire. The i reports demands for London's fire chief Dany Cotton to "resign now". The Metro sums up the position of the top brass as "hiding behind heroes".
