MPs have voted to approve a motion to renew Trident, the UK's nuclear deterrent.
472 MPs voted in favour of the plans while 117 voted against the motion to replace the four Vanguard class submarines with four new submarines which have been codenamed 'Successor'.
Production of the £40 billion fleet of submarines will take place in Cumbria at the BAE Systems plant in Barrow where 8,000 people are employed.
Construction work will begin on the successor submarines that carry the controversial Trident missiles, the Defence Secretary has said.
There's clear division over Britain's nuclear deterrent, which carries missiles as powerful as eight Hiroshima nuclear bombs.
MPs are set to vote on Monday evening whether or not to renew Britain's £40 billion Trident nuclear deterrent.
