The Prime Minister has posed for his first official photos at the start of the EU summit in Riga.
The meeting has been called to discuss relations with ex-Soviet states, but David Cameron plans to talk to as many other EU leaders as possible to open up discussions about the UK's relationship with the European Union.
He will outline changes he wants to see, including restrictions on benefits for migrants.
The prime minister said he expected "lots of ups and downs" but was focused on giving people a "proper choice" in a referendum due to be held by 2017.
