Federal Opposition Leader Tony Abbott has rejected senior Liberal Malcolm Turnbull’s calls for civil unions to be legislated in Parliament.

“I think it would be a great pity if marriage is not able to be passed in the Parliament,” he told the sixth annual Michael Kirby lecture on the Gold Coast last night.

“That opportunity to pass civil unions should be taken up.”
