The UK and France are to ink a deal under which UK nuclear warheads would be serviced in a French laboratory.

Under the potential £15bn-£20bn ($24bn-32bn) deal, France will service the UK’s 160 warheads at the Commissariat à l’Energie Atomique et aux Energies Alternatives, which maintains French nuclear warheads, according to Reuters.

UK Prime Minister David Cameron has confirmed that the nuclear deterrent would be renewed based on the Trident missile system.

The UK consulted the US on the proposed agreement, since the submarine-launched Trident missiles are based on US technology and would involve sharing the system’s secrets with France.
