Liberal Democrats leader Sir Ed Davey is calling on the government to start building a “fully independent British nuclear deterrent” to end the UK’s reliance on the US.
The UK has operational control of its nuclear arsenal, including British-built warheads, but it depends on the US to supply and maintain the Trident missiles that would deliver them.
In a speech to his party’s spring conference in York on Sunday, Sir Ed will argue the UK’s continued reliance on US support is an unacceptable risk to national security.



Why not?
Britain and Poland would have to withdraw from the Treaty on the Non-Proliferation of Nuclear Weapons. The only state to do so to date is North Korea and it would be a highly troubling precedent.
