Anti-Brexit campaigners demanding that Boris Johnson leave the “grace and favour lad pad” he is still living in almost three weeks after resigning as foreign secretary have offered him a helping hand.

A handful of protesters parked a van with the slogan “Leave Means Leave Removals Ltd” outside the foreign secretary’s official residence at Carlton Gardens, central London, which Mr Johnson has yet to move out of.

Campaigners from For our Future’s Sake (FFS) and Our Future our Choice dressed up in overalls and brought cardboard boxes to the gates of the residence on Thursday morning.

They rang the bell and asked if they could speak to Mr Johnson but he did not materialise.

Mr Johnson plunged the Government into crisis after he announced he was quitting, with a scathing denunciation of the Prime Minister’s Brexit plans.

But despite quitting, Mr Johnson has not yet left the official home situated not far from Buckingham Palace and The Ritz Hotel.

Richard Brooks, co-founder of FFS said: “In typical Boris Johnson fashion, he wants to have his cake and eat it.

“We at FFS know how important leaving is to Boris so we’re here today to help him move out. We’ve got the van, the boxes, the bubble wrap and though we’re not quite the professional photographers he’s used to, we’ve got decent camera phones.”

Mr Brooks, 26, from Dover, was one of four campaigners at the stunt, and said the main objective of the groups, under the umbrella of People’s Vote, is to get a vote on the final Brexit deal.

It is understood Mr Johnson is expecting to move out around the end of July.

A Foreign Office spokesman said: “Former ministers are expected to leave official residences as quickly as practicable at the end of their tenure, taking into account their personal circumstances and family requirements; we can confirm there is no additional cost to taxpayers involved.”

He is not the first foreign secretary to stay in the residence for a period after his tenure.

When Robin Cook was ousted from the Foreign Office and demoted to Commons leader in 2001 he was allowed to hang on to a “granny flat” above the new occupant in Carlton Gardens for two years.
