Malcolm Turnbull is standing by the coalition government's commitment to hold a national plebiscite on legalising same-sex marriage after the next election.
Deputy Labor leader Tanya Plibersek asked whether the prime minister will allow a free vote on same-sex marriage, saying Liberal MP Warren Entsch's bill currently before the parliament could go to a vote as early as tomorrow.
Mr Turnbull responded by confirming the government's policy still stands and the matter will be resolved via a plebiscite following the next election.
