The Conservatives have been looking for a big name defection since Cameron became party leader. So far, certain LibDems have resisted the lure and even the Prince of Darkness Peter Mandelson has been touted (but refused by most sane Tory members).
I am pleased that tomorrow the defection will come in the shape of former Ulster Unionist Leader and peer (Lord) David Trimble. Trimble is the one of the most measured and intelligent politicians of his generation - a nobel prize winner and a man of principle. He is welcome into our party with open arms.
This defection may not surprise those who know Trimble closest nor will it send out that many shockwaves, but I alsways think you know somebody by who their friends are.
And if Cameron is bringing people like David Trimble into the party then that is very good news for us indeed.
