Is he in the right Party

Now to be fair, John Redwood's whole Welsh sojurn was destroyed by one painful rendition of the anthem Hen Wlad fy Nhadau(see this Youtube film for the memory). But he has broken ranks with Conservative high command by advocating the UKIP policy on the devolved government's of Scotland Wales and Ulster.
"The sooner we move to a country where Westminster MPs are dual role, meeting as the Scottish Parliament in Edinburgh, the Welsh Assembly in Cardiff, the Northern Ireland Assembly in Stormont and the English Parliament in Westminster as well as meeting together as the Parliament of the Union, the better".

Given that he also supports a raft of other UKIP policies, one has to wonder why he is still in a party that has left him behind in their scrabble for the ill defined middle ground?
