The environmentalist group Greenpeace has acquired the infamous “£350 million a week” bus owned by campaign group Vote Leave.

The coach was subject to intense criticism during the EU referendum campaign because it bore text falsely claiming that Britain paid the EU £350 million a week.

Campaigners such as Boris Johnson and Iain Duncan Smith suggested the NHS could be given the money instead.

Greenpeace is redecorating the bus with the words “Time For Truth” and “#comeclean”, and is soliciting other messages from members of the public to put on the side.

The repainting and covering occurred within sight of Parliament on Monday morning.

The environmental campaigners tracked down the vehicle last week, they said. They have not purchased it and are renting it from the company that owns it.

Greenpeace executive director John Sauven called for clarity on what the next steps were after Brexit.

“The referendum campaign was marred by exaggerations and lies, and now we need the truth,” he said.

“That's why we're covering Boris Johnson's battle bus with thousands of questions for the new Government from Leave and Remain voters.

"They want to know what the Government will do about air pollution and climate change after we Brexit. Some just want to know if their European friends will be allowed to stay here.
