Senior local Conservatives are urging the prime minister to delay any parliamentary decision on gay marriage until after the next election.
More than 20 current and former constituency chairmen have delivered a letter to 10 Downing Street.
It warns of "significant damage to the Conservative Party in the run-up to the 2015 election" if the plans enter law.
One of the signatories of the letter, Conservative councillor Ben Harris-Quinney, said there was no mandate for it.
