Twenty Conservative MPs have rebelled against their own party and voted with the opposition yesterday in favour of an amendment to the latest Finance Bill; the first time the UK Government has lost a Finance Bill vote since 1978 – 41 years ago.

The amendment, put forward by Labour’s Yvette Cooper, won with 303 for and 296 against, hitting Theresa May with yet another Commons defeat. The addition will now limit the government’s capacity to change taxes in the event of a no-deal Brexit by requiring parliamentary approval.

The 20 Tory rebels were:

  • Sir Michael Fallon
  • Justine Greening
  • Dominic Grieve
  • Ken Clarke
  • Sir Oliver Letwin
  • Nicky Morgan
  • Dr Sarah Wollaston
  • Nick Boles
  • Sir Nicholas Soames
  • Sam Gyimah
  • George Freeman
  • Anna Soubry
  • Heidi Allen
  • Guto Bebb
  • Richard Benyon
  • Jonathan Djanogly
  • Phillip Lee
  • Bob Neill
  • Ed Vaizey
  • Antoinette Sandbach

Commons records show that 13 Conservatives, 24 Labour MPs, and 3 independents did not vote on the amendment, while three Labour MPs - Kate Hoey, Graham Stringer, Ronnie Campbell – voted with the government.

11 of these Conservative rebels had also signed the initial amendment, including Nicky Morgan – a former cabinet minister, Dr Sarah Wollaston – Chair of the Select Committee, and Sir Nicholas Soames. One of those who voted against the government, Sir Oliver Letwin, says he still supports both Theresa May and Brexit, but insists that MPs must choose her deal and not allow a “chaotic” no-deal scenario.

Speaking about her amendment, Yvette Cooper warned fellow members of parliament not to allow no-deal to happen "by accident or through brinkmanship", saying: "Whilst this amendment only applies to the Finance Bill, and whilst there are still a wide range of different views on the best way forward, it shows that enough MPs are ready to come together in a sensible way to oppose a chaotic no-deal”.

A spokesperson from No10 Downing Street said that the defeat was more "inconvenient rather than significant", with some – including former Tony Blair and Gordon Brown adviser Theo Bertram – pointing out why Yvette Cooper’s amendment victory isn’t as impactful on the government as it is embarrassing to them.

The issue for opposition parties and Tory rebels is how to move on from protest votes, such as this, to more substantive action. The rules of Brexit are that, until otherwise stated, the UK’s departure from the EU will happen – with or without a deal. This is as per Article 50 of the Lisbon Treaty.

There are three ways to avoid this situation: back May’s deal, extend Article 50, or revoke it altogether. The European Court of Justice has ruled that the UK can remain in the EU and abandon Brexit and can do so without needing the approval of the other 27 EU member states.

Support for May’s deal is all but non-existent but cancelling Brexit will need one of two things: a general election and a new government to be formed, or more likely a second referendum. This option would still be problematic. Leave voters are already arguing that they aren’t being listened to and that they voted democratically. The Brexit referendum wasn’t legally binding, so there’s no legal reason why a second referendum couldn’t happen, but given the fierce societal divide already being witnessed it would likely ramp up tensions further. There have been rumblings since early December that a vote of no confidence may be pursued by opposition parties after the vote on Theresa May’s Brexit deal, so perhaps such an action could be taken when the vote finally happens next Tuesday.
