Story summary

Sir Ed Davey, leader of the Liberal Democrats, called for the UK to develop a fully independent nuclear deterrent to end its reliance on the United States, in a speech at the party's spring conference.
He argued the Trident system is not genuinely independent because it depends on US manufacture and maintenance.
He warned that unpredictability in US leadership under U.S. President Donald Trump poses a national security risk.
He proposed immediate steps to establish a British maintenance program and to develop a domestically produced alternative by the 2040s.

History

Historical Context

The UK's nuclear deterrent strategy evolved significantly after it became the third nation to develop nuclear weapons in 1952. Following the cancellation of the Blue Streak missile in 1960, the UK secured the Polaris submarine program through the Nassau Agreement with the U.S. in December 1962, reflecting ongoing concerns about reliance on American military support and shaping future defense policies.
