Secretary of State for Environment, Food and Rural Affairs Michael Gove claimed that the Parliament could simply "undo" the Chequers deal once the UK has left the bloc.
According to the official, the plan is permanent, but might be changed in future.

"The Chequers approach is the right one for now because we have got to make sure that we respect that vote and take advantage of the opportunities of being outside the European Union," Gove told the BBC, adding that "a future prime minister could always choose to alter the relationship between Britain and the European Union."
The Brexit deal between London and Brussels is expected to be finalized by the end of October, with the United Kingdom leaving the EU on March 29.
