A top pollster has retracted his claims that YouGov had been 'blocked' from releasing a poll during the 2017 General Election campaign because it was "too positive about Labour ".
Chris Curtis, who is now head of political polling at Opinium, initially said on Wednesday Nadhim Zahawi had threatened the CEO of YouGov and would "call for his resignation" if the pollsters predictions of a hung parliament were wrong.
Mr Zahawi swiftly dismissed the threats, claiming it was "clearly a joke between two good friends" who had worked as business partners for some time.
