The Guardian reports Tories Hit by New Defections and Slump in Opinion Polls as Party Divide Widens.

The bitter fallout from Brexit is threatening to break the Tory party apart, as a Europhile former cabinet minister Stephen Dorrell on Sunday announces he is defecting to the independent MPs' group Change UK, and a new opinion poll shows Conservative support plummeting to a five-year low as anti-EU parties surge.

The latest defections come as a new Opinium poll for the Observer shows a dramatic fall in Tory support in the past two weeks and a surge for anti-EU parties. The Conservatives have fallen by six percentage points to 29% compared to a fortnight ago. It is their worst position since December 2014. Labour is up one point on 36% while Ukip is up two points on 11%.
