The member of the European Scrutiny Committee has said that the further extension of Article 50 is a “complete and total travesty of constitutional arrangements”.
On Monday night, a bill put forward by Labour MP Yvette Cooper to extend Article 50 in a bid to avoid a no-deal Brexit received royal assent and became law.
There is now a legal requirement on Theresa May to seek an extension to Article 50 to prevent a no-deal Brexit.
Mrs May has already requested a further extension of the Brexit deadline to June 30, despite European Council president Donald suggesting that EU leaders should grant the UK a longer extension of up to one year.
Conservative MP Bill Cash told talkRADIO’s Julia Hartley-Brewer: “This extension is just to bide time. The Remainers in the House of Commons have been working to overturn our constitutional conventions in order to get precedent for their legislative arrangements over the government.
“It is a complete and total travesty of our constitutional arrangements. It is an outrage.”
The MP for Stone has said the extension of Article 50 was a result of Conservative Remainers “voting with Corbynites”.
Mr Tusk, in a letter to the heads of the 27 remaining member states, said there was "little reason to believe" that the ratification of Mrs May's Brexit deal could be completed by the end of June.
He called for the European Council to discuss an alternative, longer extension, such as a "flexible extension" lasting "as long as necessary and no longer than one year".
