General Election: Where are all the celebrity endorsements this time?

If in 2015 celebrity endorsements helped shape a pre-Brexit election, this time no one seems too worried about swaying the result.

Where is Russell Brand and his quest to "end the danger of the Conservative party?" Or Joey Essex's selfie sessions with Nick Clegg? Or Simon Cowell praising the Tories?

With less than a month to go before Britain heads to the polls, celebrities' social media accounts have gone silent, void of political opinion.

When Theresa May announced she was calling a snap general election last month, some immediately tweeted a response.

"It's my fault. Last time I was in Britain a referendum gave us Brexit," Stephen Fry wrote.

"Then I went to the US & Trump happened. Now I come home and…"

Lily Allen, a long-time critic of the Prime Minister, urged her fans to vote for grime artist Stormzy.

But apart from the occasional joke, not much else has been said.

Granted, Ken Loach is still actively calling for Jeremy Corbyn to stay as Labour leader, using the hashtag #MayDay on his Twitter feed and warning of the dangers of voting Conservative.

But the filmmaker was a politician before and during his years behind the camera.

Still, Labour seems to be the party gathering the most celebrity endorsements this year, with snooker champion Ronnie O'Sullivan tweeting: "Just joined the Labour Party to support Jeremy Corbyn to be the next prime minister".

On the Conservatives side, comedian Jim Davidson seems to be one of the few still retweeting Tory promises on his feed, while criticising Labour's economic policy of "higher taxes, more debt and economic chaos".

But A-listers such as Sir Ian McKellan, Joanna Lumley and Russell Brand seem unusually quiet.

Now, Brand seems to be entirely dedicated to his radio shows and guest appearances on Twitter - he's still debating politics but with a more unbiased approach.

One sub-group which has suddenly gained a strong political voice is grime.

Artists such as JME and Stormzy, who came from working class Britain to the heights of celebrity status, are backing Mr Corbyn and urging people to register to vote.

The effort even granted a response from the Labour leader, who tweeted back to rapper JME saying "thanks for the support".

Stormzy is also supporting Labour - despite receiving Allen's tongue-in-cheek endorsement.

"My man, Jeremy! Young Jeremy, my guy. I dig what he says. I saw some sick picture of him from back in the day when he was campaigning about anti-apartheid and I thought: yeah, I like your energy," he told The Guardian.

As for the Lib Dems, they are unprecedentedly short of celebrity backing.

Supporter John Cleese has been criticised for becoming "less subversive" and "joining the establishment".

"If you really think I've become less subversive you are either extraordinarily unperceptive or completely misinformed," the actor replied.

And Piers Morgan, who is never short of an opinion on politics - or anything else - has focused all his recent attention on actress Emma Watson and her "public pontificate" .

"Every time I hear the actress - sorry, gender-equal actor - Emma Watson pontificate in public these days, I just die a little bit more," he wrote.
