Green Party leader Natalie Bennett has said she is open to discussing the possibility of legalising three-way marriages.
Bennett said she was "open to further discussion and consultation" on the issue after being asked whether the Greens would support group civil partnerships and marriages.
She was quizzed by a Pink News reader who said he was living with two boyfriends in a stable long-term relationship and asked: "Is there room for Green support on group civil partnerships or marriages?"
Bennett replied: "At present, we do not have a policy on civil partnerships involving more than two people. We are, uniquely in this country, a party whose policies are developed and voted for by our members.
"We have led the way on many issues related to the liberalisation of legal status in adult consenting relationships, and we are open to further conversation and consultation on this issue."
