Hundreds of thousands of votes have been lodged in an Australian Labor Party (ALP) social media poll on marriage equality.

The huge response comes just a day before federal MPs are due to speak in Parliament on the same-sex marriage views of their electorates.

The ALP Facebook account asked users ‘Should Same-Sex Marriage be legal in Australia’. Nearly 200,000 votes have been lodged in the poll, with a clear majority in favour. At current count there are 161,150 ‘yes’ votes and only 34,356 opposed.
