Gay marriage 'a ploy to rebrand Conservatives' The ComRes poll, published by the Coalition for Marriage campaign against the reforms, surveyed 2,000 adults earlier this month. Asked whether "marriage should continue to be defined as a lifelong exclusive commitment between a man and a woman," 62 per cent of respondents agreed. Sixty - five per cent agreed with the statement: "David Cameron's plan to legalise gay marriage is more to do with trying to make the Conservative Party look trendy and modern than because of his convictions." Only 23 per cent thought that the Chancellor, George Osborne, was correct to argue that legalising same-sex marriage would help the Tories win the next election.
