On 13th December, 11 Tory rebels supported an amendment by Dominic Grieve, resulting in Terri May's first defeat in the commons. The 11, comprising:
Grieve, Anna Soubry, Ken Clarke, Nicky Morgan, Antoinette Sandbach, Stephen Hammond, Heidi Allen, Bob Neill, Sarah Wollaston, Jonathan Djanogly and Oliver Heald, were all members of the 15 mutineers, identified by the Telegraph in November.
Of the other four mutineers, Vicky Ford, Jeremy Lefroy and Tom Tugendhat all voted with the government, while Paul Masterton is not listed as having voted.
Another Conservative MP, John Stevenson, abstained by voting in both lobbies.
Two Labour MPs, Frank Field and Kate Hoey, voted with the government.
The vote was 309 for the amendment, 305 against.
