David Cameron insists that despite concerns from other members of his party "now is not the right time to leave Britain".
When questioned on the BBC's Andrew Marr Show, the Prime Minister said that "fifty percent of Britain's trade currently happens with Europe" and so it was very important that "Britain retains it's seat at the table".
Mr Cameron said that despite Britain's trade agreements, as long as he stayed Prime Minister the country would not convert its currency to the Euro.
