The UK Daily Mail reports that UK prime minster David Cameron's risky gay marriage gamble is turning into a political disaster for him:

The full extent of the revolt among Tory MPs over plans to allow gay marriage was revealed last night. In all, more than 100 Conservatives out of 303 have written to constituents indicating their unease. If they all vote against, it would be the biggest Tory rebellion in modern times.

Backbencher Douglas Carswell, one of those who will vote against, said: ‘I think you’ve got to have your head stuck in the Westminster bubble to think this is a priority.’

The vote could happen as early as January after Mr Cameron decided this week to ‘get it done and get it done quickly’.

They are an eclectic bunch – including a former breakfast TV presenter, a former top City investment manager, a Liverpool football fan and a gay friend of Margaret Thatcher.

But all have one thing in common: they are among the many Tory MPs who bitterly oppose David Cameron’s controversial policy to make gay marriage legal.

Altogether, there are at least 118 Tory MPs (out of a total of 303) who, the Mail can reveal, have condemned the proposal to redefine the centuries-old institution of marriage.
