Jo Johnson resigned as Britain’s transport minister on Friday, branding the proposed Brexit deal a “terrible mistake” that necessitated a fresh referendum on leaving the E.U.
Johnson — who had backed staying in the bloc in the 2016 referendum — is the younger brother of Boris Johnson, who spearheaded the pro-Brexit campaign and quit as foreign secretary in July over Prime Minister Theresa May‘s Brexit blueprint.
“It has become increasingly clear to me that the withdrawal agreement, which is being finalized… will be a terrible mistake,” he wrote in a stinging resignation statement.
“It is entirely right to go back to the people and ask them to confirm their decision to leave the E.U. and if they choose to do that, to give them the final say on whether we leave with the prime minister’s deal or without it,” he added.
Prime Minister May is reportedly close to securing a divorce deal with Brussels, as time runs out ahead of Britain’s planned departure from the E.U. on March 29 next year.
The agreement will finalize Britain’s exit bill of around £39 billion ($50 million), guarantee citizens’ rights and see a 21-month transition phase during which London will follow E.U. rules.
British and European negotiators will then seek to agree on the long-term future relationship.
But in his resignation statement, Johnson said the mooted deal would leave Britain “economically weakened, with no say in the E.U. rules it must follow and years of uncertainty for business”.
He added the alternative of no-deal would “inflict untold damage on our nation”.
“To present the nation with a choice between two deeply unattractive outcomes, vassalage and chaos, is a failure of British statecraft on a scale unseen since the Suez crisis,” Johnson said.
