Nick Boles, Tory MP for Grantham and Stamford, has resigned his conservative association on the ground after publicly arguing his position on Brexit.
Boles, who has represented the constituency since 2010, is at the forefront of Parliament's efforts to soften the EU's exit, and in January, along with Yvette Cooper of Labor, sponsored an amendment that would put Parliament in control of the Brexit process can give.
He had been confronted with the efforts of local activists from the Grantham and Stamford Conservative Association to dismiss him as candidate of the party for the next parliamentary elections.
In a letter received by the BBC, Boles said, "I am not prepared to do what is necessary to establish a reasonable working relationship with a group of people whose values and beliefs are so closely aligned with my own."
He said to his local party, "I regret that my relationship with you should end this way. But a politician without principles is worthless. I have no doubt about my duty to remain true to my convictions and devote the rest of my time in Parliament to the best interest of the people for whom I was elected. "
Boles said he would remain a member of parliament and continue to take the conservative whip in Westminster "if offered to me on acceptable terms". Julian Smith, the chief whip, made it clear that Boles was "a valued member of the Conservative Parliamentary Party, which I hope will continue to benefit from his ideas and drive."
However, a high-ranking official from the local Boles association said they had been betrayed and asked him to take the "honorable course" and dismiss as a deputy.
Boles' resignations began in February when his local party voted to find a candidate, which meant he had to stand for a new election.
Boles has insisted that he does not obstruct the Brexit trial, but is vehemently opposed to a no-deal exit.
"While I have consistently argued that Brexit must be delivered, I voted in favor of the Prime Minister's deal each time she took him to the House of Commons, but I'm sure a crash from the EU would be without an EU deal would do great harm to British people and have done everything in my power to prevent it, "he wrote.
Cllr Martin Hill, vice president of the Grantham and Stamford Conservative Association, told local party members, "As you all know, Nick has been at odds with the local party and the prime minister for some time, so this announcement does not the timing leaves much to be desired.
"I understand that it is Mr. Boles's intention to remain as MP for Grantham and Stamford until the next parliamentary elections, even though he was elected to represent us in Parliament."
