A piece on the website of the Spectator in its blogs section, published on 16th February, ahead of the official announcement about the referendum, lists the Conservative MPs in the various camps “Yes”, “No” and “undecided”. The list pre-dates the actual announcement of the referendum date – I note that the list does not have the Attorney General’s stance listed correctly. Jeremy Wright was in my house at Taunton School four years above me – as the news broke of the referendum date, BBC had him in the “In” / “Yes” camp, while the Spectator’s blog had him in the “Out” / “No” camp.
I noticed that Rebecca Pow, the sitting Conservative MP for Taunton Deane (the last constituency in which I voted) has yet to decide. Liam Fox and Jacob Rees-Mogg, also in Somerset are in the “no”/”out” camp.
