Tory Whip Gareth Johnson has resigned from the government to resist Theresa May's Brexit deal at this week's significant vote.

The Dartford MP, who voted in favor of the referendum in 2016, wrote a letter to the Prime Minister, saying the backing in his agreement: "Our country does not have a clear, unilateral way out of the European Union and ensures that we are bound to it. " Negotiate trade agreements ".

"This agreement prevents us from taking back control and could instead have been constantly restricted by the European Union," he said. "Like you, I am not only a conservative but also a dedicated trade unionist, and I can not accept the additional regulatory requirements demanded by Northern Ireland that would distinguish it from the rest of the United Kingdom."

He said the move was "perhaps the most difficult decision I've ever made," he added, "I decided it was time to turn my loyalty to my country over my loyalty to the government."

Mr. Johnson initially said he hoped "hopefully that changes could be made" to improve the way Ms May interacts with the EU.

However, he said: "It is now clear to me that no substantial change will be made to this agreement before the meaningful vote takes place.

"However, I hope that even at this late stage, efforts will continue to change the terms of this agreement and its implications for our country.

"We must rediscover our trust and faith in our ability to survive in the world without the European Union controlling and managing our future."

Just over 65 percent of Mr. Johnson's constituency Dartford voted in the 2016 Brexit referendum.

In his letter he added: "Together with nearly two-thirds of my voters and a majority of the country, I supported the" absence "in the referendum, because I wanted Britain to regain the sovereignty we lost during our membership of the European Union had.

"Unfortunately, this agreement prevents us from regaining control and instead being constantly restricted by the European Union."

Mr Johnson was announced when Mrs May received a joint letter from European Council President Donald Tusk and European Commission President Jean-Claude Juncker, saying that they were 'unable to' to rewrite or amend the readmission agreement secured last year.

However, they assured the Prime Minister that the EU "did not want to put the backing into effect" as this would be a "suboptimal trade agreement for both sides".

The EU Presidents stated: "If the backstop is to come into full or partial effect, it should be applied on a temporary basis, unless it is replaced by a subsequent agreement."
