No 10 rebukes Nick Clegg over his attack on PM's Europe speech It is really important to take a lead in those debates and make the changes that he believes would be right for Britain. The Prime Minister and Deputy Prime Minister have discussed their respective approaches to the European Union on a number of occasions. Mr Cameron is expected to "share the specifics of the speech" with Mr Clegg before he delivers his remarks, but will brief Conservative Cabinet ministers on its contents tomorrow. The Prime Minister is under pressure from his own backbench MPs and other senior Tories to call a referendum on Britain's membership of the EU. He has said he favours remaining in Europe but intends to repatriate some powers and seek "fresh consent" from British voters for a new relationship with the EU focused on trade links. The Prime Minister will make a speech setting out Britain's relationship with the European Union in Amsterdam this Friday. Mr Clegg warned that the continuing debate over Britain's relationship with Europe was creating a climate of uncertainty that undermined confidence in the economy. "We should be very careful, at a time when the British economy is still haltingly recovering from the worst economic shock for a generation, to create a very high and prolonged period of uncertainty," Mr Clegg told BBC Radio 4"s Today programme. Our priority in this Government has got to be to foster jobs and growth and if you're an investor investing in the United Kingdom to create jobs here, I think it is unnecessary to create a high degree of uncertainty that might actually chase away investment and might diminish the number of jobs in this country," Mr Clegg said.
