ANY MP that doesn't accept Brexit should resign– that is the message from Richard Drax.

Mr Drax, MP for South Dorset, voted for the UK to leave the EU in the referendum in June.

He has now penned a letter which says some MPs are attempting to 'water down' the historic vote by 'attaching amendments to any Bill that might have to pass through the House to invoke Article 50.'

Britain's complex negotiations to exit the EU can only begin when Article 50 of the Treaty of Lisbon is formally triggered by the UK.

Prime Minister Theresa May said she would trigger Article 50 no later than March 2017, meaning the UK could be out of the EU by April 2019.

But the government was subject to a legal challenge over whether it has the right to trigger Brexit without the consent and authorisation of Parliament.

The argument has now been taken to the Supreme Court after the High Court ruled that the government could not trigger Brexit without MPs voting.

The Supreme Court's ruling will affect Theresa May's plans for how Brexit will go, but it is not a decision about whether it will happen or not.

A total of 460 MPs want the Prime Minister to stick to her proposed timetable of triggering Article 50 by March. But 89 MPs have rebelled and voted against.

Mr Drax wrote in the Telegraph letters section yesterday: "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 prevent, exit.

"MPs in particular contemplating such action should think carefully of the consequences, as the country is not in the mood for prevarication, nor can it afford to delay any longer.

"Resignation is the only honourable path for those who cannot and will not accept the result of the referendum."

Speaking to the Echo today he said he is not saying people can't debate Brexit or 'speak their mind' and that there will be opportunity to do so, but that shouldn't be done when discussing invoking Article 50.

But 'if we can't give the country what it wants and what it voted for, then those who are trying to thwart it should do the honourable thing.'
