Building on the Lancaster House treaty signed in 2010, the agreements further the security and prosperity of the 2 nations through commitments to jointly invest in the procurement of defence equipment, the joint training of armed forces and the continued development of the Anglo-French Combined Joint Expeditionary Force.

Both countries have signed:

• a statement of intent for a future combat air system, which would launch a 2-year, £120 million joint feasibility phase that will see British and French industries working together

• technical arrangements for our exchange programme to provide RAF pilots and engineers with experience of operating the A400M ahead of the delivery of the UK’s first aircraft later this year; and for French pilots to gain flying experience on the RAF’s A330 Voyager aircraft

• a memorandum of understanding confirming joint orders for a future helicopter-launched, anti-surface guided weapon for our navies

Agreements have also been reached that will see:

• a £10 million contract for the development of underwater vehicles capable of finding and neutralising seabed mines

• investment in the Atomic Weapons Establishment at Aldermaston, Berkshire, to allow collaboration on and safe testing of UK and French stockpiles and greater sharing of technical and scientific data to further joint research

• further co-operation between both armies in the areas of equipment capability and interoperability

Both countries also agreed to build on international peacekeeping missions carried out by their respective forces in Libya, Mali and the Central African Republic.

Defence Secretary Philip Hammond and his French counterpart, Jean-Yves Le Drian, agreed to continue the development of a Combined Joint Expeditionary Force capable of carrying out co-ordinated expeditionary military operations.

The 2 nations also agreed joint efforts to tackle security issues in north and west Africa, in particular terrorism, as well as drug and arms trafficking to achieve long term stability in the regions.

Mr Hammond said:

Britain and France are natural partners for defence co-operation. We have made substantial progress since the Lancaster House treaty was signed in 2010 and today we have committed ourselves to go further still.

The agreements we have reached at this summit will improve the interoperability of our forces, enhance our joint equipment procurement and build on our capacity to support security and stability in places such as Libya, Mali and the Central African Republic.
