Douglas Carswell defection: the Europe 'bomb' goes off
This is a body blow for David Cameron.

Who will rid me of this troublesome court?
That's the question David Cameron badly wants an answer to before the next election.
Michael Gove - Down but not out
It is no exaggeration to say that many teachers will be celebrating the cabinet reshuffle tonight.
"Gove has gone" they will shout as they pour themselves another glass. Which is why, of course, the education secretary had to go.
Reshuffle: Who will be the winners?
On Monday the losers learnt their fate.
