He said January 31 will be "a significant moment in our country's history" and details of the official events will be announced "shortly".

But he refused to say whether the Government will support a campaign by Brexiteer MPs to get Big Ben to bong as the hour strikes 11pm on January 31 - the exact time Britain's membership of the EU lapses.

Brexit Party leader Nigel Farage is planning a £100,000 party in Parliament Square on the night - with fireworks, bands and speakers.

He said the event would be an upbeat, optimistic, genuine celebration with no direct political edge whatsoever".

A senior Whitehall source distanced the Government from the event, telling The Sun: "There'll be something but i wouldn't go down the road of a Farage-style street party.

The Prime Minister's spokesman said: “In terms of our departure on 31 January, we will set out our plans shortly.

“It’s clearly a significant moment in our country’s history, but we will set all of our plans out shortly.”
