Jeremy Corbyn claimed Theresa May tried to “take powers away” from Parliament and said David Davis will no longer be left to approve a Brexit deal “on his own”. 

Theresa May suffered her first defeat over an EU withdrawal bill amendment put forward by Tory rebel Dominic Grieve.  

Dominic Greive told MPs it was time to “stand up and be counted” as he pushed to have a “meaningful vote” on Brexit. 

Speaking to Sky News, Mr Corbyn said: “The Prime Minister tried a power grab. She tried to push through an EU withdrawal bill without proper Parliamentary scrutiny and take powers away from Parliament. 

“Parliament resisted tonight and won a vote which says there has to be a proper decision by the British Parliament on the terms and what happens over the negotiations on Brexit. 

“It’s not all going to be left to David Davis on his own.” 

The defeat is likely to slow down the Brexit process and comes ahead of Thursday’s EU Summit – where EU leaders are expected to authorise talks are ready to move on to trade. 

MPs voted on Wednesday 309 to 305 in favour of an amendment tabled by a group of Tory MPs against the EU Withdrawal Bill. 

The European Union’s Guy Verhofstaft wrote a mocking tweet targeting Theresa May following the Brexit defeat. 

He wrote on Twitter: “British Parliament takes back control. European and British Parliament together will decide on the final agreement.

“Interests of the citizens will prevail over narrow party politics. A good day for democracy.” 

The government was "disappointed" by the vote, a spokeswoman said in a statement, adding that "this amendment does not prevent us from preparing our statute book for exit day".
