Defence Secretary Michael Fallon welcomes decision to renew the UK's continuous at sea deterrent.
Defence Secretary Michael Fallon said:
MPs on all sides have voted by an overwhelming margin, to renew our nuclear deterrent - the ultimate guarantee of our national security.
We have voted to protect our nation from the most serious threats we may face in the 2030s, 2040s and 2050s.
The British Parliament has sent a powerful message to our allies that Britain is stepping up its international commitments, not stepping back from them.
We will now get on with building the next generation of nuclear submarines to help keep the nation, and our allies, safe for decades to come.
