The pro Brexit MP wrote on Twitter: “Tonight, the Tory rebels have put a spring in Labour’s step, given them a taste of winning, guaranteed the party a weekend of bad press, undermined the PM and devalued her impact in Brussels.
“They should be deselected and never allowed to stand as a Tory MP, ever again.”
This evening, MPs voted 309 to 305 in favour of an amendment to the European Union Withdrawl Bill.
This will slow down the Brexit process and comes ahead of tomorrow’s key EU Summit – where the go-ahead was due to be given to talks progressing to trade.
Ms Dorries then tweeted: “I’ve been a rebel myself, but never when a Marxist government was knocking at the door”.
The rebels who backed the amendment are:
Dominic Grieve, Beaconsfield
Ken Clarke, Rushcliffe
Nicky Morgan, Loughborough
Robert Neill, Bromley and Chislehurst
Stephen Hammond, Wimbledon
Sir Oliver Heald, North East Hertfordshire
Anna Soubry, Broxtowe
Sarah Wollaston, Totnes
Jonathan Djanogly, Huntingdon
Antoinette Sandbach, Eddisbury
Heidi Allen, South Cambridgeshire
Ms Dorries was met with a mixed reception on Twitter.
Philip Spencer said: “I agree and I will not be happy voting Conservative again unless the 12 are deselected”.
Whereas, Kev Meredith said: “They were doing their job – putting country ahead of party”.
Ms Dorries also said Dominic Grieve had committed “treachery”.
On Twitter, she said: “The Government recently nominated Grieve to be Chairman (paid) of the Intelligence and Security Committee. He has repaid that by his treachery. Were there no loyal MPs for the job?
You know, like the way Labour do it when they are in government.”
Several rebel MPs from Mrs May’s Tory party helped push through the amendment, helped by all opposition parties.
The Labour leader Theresa May mocked Theresa May after the result, staying the defeat was “humiliating”.
Tonight was a major defeat for Theresa May’s government and means she must secure parliamentary approval before signing off a final Brexit deal.
Minutes before the vote, Justice minister Dominic Raab sought to appease would-be rebels by saying the Government would rewrite the Bill to guarantee concessions it had offered but was faced with shouts of “too late” by some MPs on his side.
The Labour leader said: “This defeat is a humiliating loss of authority for the government on the eve of the European council meeting.
“Labour has made the case since the referendum for a meaningful vote in parliament on the terms of Britain’s withdrawal from the European Union.
“Theresa May has resisted democratic accountability. Her refusal to listen means she will now have to accept parliament taking back control.”
