Europe eyeing Conservative performance in UK election
Charles Grant, with the Centre for European Reform, said: "He has said that he wants to build up credibility by showing that he's a constructive European leader in the early stage of his premiership, if he indeed does become prime minister. That's encouraging but still the worry remains that after a few years he implies that he will come back to this issue of trying to change the treaties and everybody in Europe has spent about 10 years negotiating the treaty change and they're fed up with it."
