British Prime Minister David Cameron has said he is determined to reform Britain’s relationship with the EU as he begins discussions with other European leaders on his plans, BBC News reports.

At a summit in Latvia, 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.

EU leaders are in Riga to discuss relations with Eastern Partnership  states.

Mr Cameron said this issue was very important in its own right but that the gathering was also “an opportunity to start some of the discussions about reform of the EU”.
