Francois Hollande shot down David Cameron's hopes of talking about EU treaty change negotiations today.
President Francois Hollande is being plagued by affair allegations - but he is not the first French politician to be embroiled in scandal.
French magazine Closer will remove a report from its website that alleges President Francois Hollande was having an affair with an actress.
French President Francois Hollande said he is ready "to apply all the necessary pressure" in order make Russia understand that negotiation is the only option regarding Ukraine.
He made the comments during the annual dinner of the Representative Council of French Jewish Institutions in Paris.
Hollande said Russia has "taken the risk of a dangerous escalation" by deploying soldiers in Ukraine's Crimean peninsula.
"In these circumstances, France's role with Europe is to apply all necessary pressure including the possible use of sanctions to propose, to impose, a path to dialogue and to find a political solution to this crisis," he added.
David Cameron has spoken to the German Chancellor Angela Merkel and the French President Francois Hollande about the crisis in Ukraine, Number 10 has revealed.
Ahead of the meeting of EU leaders on Thursday, Downing Street said they all agreed "the international community should speak with one voice and send a clear message to Russia that its actions in Ukraine were completely unacceptable."
They also talked about the importance of "the costs and consequences for the Russian government of continuing to violate Ukraine’s sovereignty."
French journalists have indulged in a few "selfies" in the Oval office while accompanying their president, Francois Hollande, on his trip to the United States.
A reporter for Le Monde took this self portrait, with Mr Hollande and Barack Obama clearly visible in the background.
President Obama is no stranger to selfies, having controversially taken a picture of himself with David Cameron and Danish Prime Minister Helle Thorning-Schmidt during Nelson Mandela's memorial service.
The Queen will make a State visit to France from 5th - 7th June to commemorate the 70th anniversary of the Normandy landings.
After a visit to Normandy the Queen who will be accompanied by The Duke of Edinburgh will attend State Visit events in Paris and be received at the Elysee Palace by President Hollande.
French President Francois Hollande declined to answer when asked whether he was "still" having an affair with actress Julie Gayet.
The Daily Telegraph's Senior Political Correspondent Christopher Hope asked the President: "Do you think your private life has made France an international joke? Are you still having an affair with Julie Gayet? And do you wish she was here?"
The build-up to today's Anglo-French summit was dominated by allegations about Mr Hollande's private life.
David Cameron and French President Francois Hollande visited a local pub in the Prime Minister's constituency after they held talks nearby.
Defence Secretary Philip Hammond said Britain and France are "natural partners for defence co-operation" after the Prime Minister announced a series of deals.
Mr Hammond said in a statement:
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 inter-operability 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.
ITV News Europe Editor James Mates is at the press conference in Oxfordshire:
Inevitably it's left to a UK journalist to ask Hollande 'are you still having an affair with Julie Gayet, do you wish she was here?'
Hollande studiously ignores the question. Talks about European treaty change instead.
David Cameron and Francois Hollande have agreed to extend defence and nuclear co-operation between the UK and France.
The Prime Minister announced a two-year £120 million feasibility study for a new armed drone, called the Future Air Combat System, saying the two countries will work together on the unmanned craft.
He said Britain will offer more logistical support for the French military mission in the war-torn Central African Republic, and announced troops will hold a joint training exercise later in the year.
The UK will try out the French VBCI tank with a view to possibly purchasing it for the Army, he added.
