Speaking in a debate this afternoon in the House of Commons on the allegations by Shahmir Sanni about links between Vote Leave and the youth campaign group BeLeave, Shadow Cabinet Office Minister Jon Trickett said the Government is “in up to its neck”.

The Labour Party said there must be an urgent Electoral Commission investigation into fresh revelations about EU referendum campaign spending in light of a whistleblower’s claims about collusion.

Jon Trickett MP, Labour’s Shadow Cabinet Office Minister, said:

“Labour does not want to unpick or overturn the referendum result. But these issues go to the heart of the functioning of our democracy and we must establish if there has been any wrongdoing.

“The Government is in up to its neck. Two Cabinet Ministers fronted the campaign and the Prime Minister has defended her political secretary after his personalised attack on the whistleblower.

“There must be an urgent and thorough investigation and it must be wholly independent. The Electoral Commission must be given the resources and any extra powers it needs to follow wherever the evidence leads.”
