Pro-Remain MPs should resign their seats, according to Conservative MP for South Dorset, Richard Drax.

“Resignation is the only honourable path for those who cannot and will not accept the result of the referendum,” he wrote in a letter to the Daily Telegraph.

“The question put to the British people during the EU referendum could not have been simpler: in or out.

“Neither side in the argument attached any conditions. There were no ifs or buts.

“Now, encouraged by the current court action, some MPs and peers are preparing to water down that historic vote by attaching amendments to any Bill that might have to pass through the House to invoke Article 50. Clearly, their intent is to delay, or even prevent, exit.”

On Wednesday night parliament approved an amendment to a Labour bill that provisionally mandated for the triggering of Article 50 by the end of March. 89 Labour MPs voted against the motion, whose names were immediately circulated on social media by the Conservative press office. Ken Clarke was the only Conservative MP to do so.

Mr Drax’s full name is Richard Grosvenor Plunkett-Ernle-Erle-Drax but was alleged to have been asked to shorten his quadruple-barrelled before standing for election in 2010.
