Prime Minister David Cameron spoke with President Hollande in the margins of the Battle of the Somme centenary commemorations in France.
A Downing Street spokesperson said:
The Prime Minister held talks with President Hollande in the margins of the Somme centenary commemoration event in France today.
They agreed the bilateral relationship between the UK and France was enduring and strong, and that our defence and security cooperation in particular would continue to go from strength to strength, based on the solid foundation of the Lancaster House Treaty.
They agreed a mutual commitment to continue working closely together to protect our shared border in Calais and to maintain the so-called ‘juxtaposed controls’.
They discussed Hinkley and agreed that there was continued UK and French support for the project.
The Prime Minister also reiterated his view that the UK should seek the closest possible relations with the EU and in that context, the need for constructive post-referendum negotiations.
