David Cameron today compared himself to action hero Tom Cruise in his mission to overhaul Britain 's relationship with Europe . The Prime Minister said a Tory victory in the General Election would give him a 'very powerful mandate ' to win sweeping reforms and insisted it was possible . It came after Donald Tusk , the Polish president of the European Council which represents EU leaders , said rewriting the EU treaties to curb migration would be 'close to Mission Impossible ' for Mr Cameron . But the PM told a press conference in Brussels : 'Tom Cruise normally prevails in the end . He 's a little bit smaller than me , but I hope to be just as effective . ' David Cameron , pictured in Brussels today , has compared himself to action hero Tom Cruise in his bid to overhaul Britain 's relationship with Europe . Mr Cameron urged voters to the election as an 'opportunity to make sure the problems that bedevil Britain 's relationship with the EU are dealt with ' , he said . He said : 'The moment of truth is fast approaching , ' he said . 'One of two people will represent Britain in Europe after the election . It 's either me or Ed Miliband . 'If you send me back here as Prime Minister on 8 May , I have a very clear plan . I want to sit at that negotiating table with a mandate from the British people to reform the EU and fundamentally change Britain 's relationship with it . 'For too long this issue has been swept under the carpet and I believe it is time to deal with it . If I am returned as Prime Minister , that is what I will do . 'So I say to the British people : give me another term and I will give you your say on Europe . ' Mr Cameron said there were other EU leaders 'who will breathe a sigh of relief ' if he is not re-elected . The Prime Minister 's remarks came after Mr Tusk said he was 'ready to help Cameron ' – but dismissed his chances of negotiating a new European treaty within the next two years before holding an EU referendum . The former Polish prime minister said it would be hard to find agreement among all 27 EU leaders that would satisfy Mr Cameron . He said : ' I have no doubt that we have to help in a limited and rational framework . We have to help David Cameron because he is obviously pro-European . But Mr Tusk added : ' I am sceptical when it comes to changing the treaty . ' Donald Tusk , the Polish president of the European Council which represents EU leaders , greeted Mr Cameron today after claiming that his bid to rewrite the EU treaties to curb migration would be 'close to Mission Impossible ' Mr Cameron wants a new Brussels treaty to nail down a series of changes allowing Britain to limit benefits for EU migrants . The PM has insisted that new rules are needed to help the crisis-hit Eurozone , giving Britain the chance to renegotiate its relationship with Brussels . But Mr Tusk said : 'My intuition is that treaty change is close to mission impossible today because it 's not only about rationality , about good argument . 'We need unanimity between 28 member states , in the European parliament , in 28 national parliaments in the process of ratification . To say that it is a Pandora 's Box is too little . ' Mr Tusk said : 'First of all we need more precise concrete [ details ] about British demands . 'When we have more information about details , about legal problems , then we can decide if discussion about treaty change is at all necessary . 'For me the problem of possible treaty change is a practical question . It 's not only about the arguments of Cameron . I can agree or disagree with some of them . 'But at the end of the day I would like to ask him 'what is your concrete proposal ? ' and then I can consult with the other member states . ' But he said : 'We need , also for the United Kingdom , a good solution for Cameron and Great Britain under existing law , ' he said . 'We need the United Kingdom in Europe . For me there 's no more obvious political thesis than this one . And I feel , but it 's not my role to decide about it , but I feel that the United Kingdom needs Europe . ' The former Polish prime minister 's remarks are the first since he took over as European council president in December . He also admitted , in an interview with the Guardian , that he will find it hard to crack down on immigration – because of the number of Poles living and working abroad . He said : 'It 's not easy for me because of some expectations close to the immigration problems , which means also the huge Polish minority in Great Britain . '
EU chief Donald Tusk said it would be 'Mission Impossible ' for Cameron . PM wants to renegotiate Brussels 's relationship with Britain before 2017 . Mr Cameron has vowed to hold an in-out referendum on the new deal . Today he insisted he wanted to be 'just as effective ' as Tom Cruise .
