UK needs nuclear deterrent independent from US, Ed Davey to say

Lib Dem leader will tell spring conference Britain can no longer rely on US while Donald Trump is president

Britain should have a completely independent nuclear deterrent as it can no longer rely on the US, Ed Davey is expected to say on Sunday.

In a speech at the Liberal Democrats spring conference, the party leader will argue that the UK should manufacture and maintain its nuclear weapons in Britain, a move that Davey acknowledges will cost billions.
