THE independent state MP Clover Moore has moved to shore up support for her same-sex adoption bill by giving church adoption agencies the right to refuse services to gay and lesbian couples without breaching anti-discrimination laws.

Ms Moore wrote to MPs on Friday announcing she would amend the bill and reintroduce it to Parliament on Thursday.

Clover Moore . . . moved to guarantee support.

She told the Herald she was amending the bill "in line with requests" from church adoption agencies to help ensure its passage through Parliament.

"Some members of Parliament have told me that they will not support reform without an exemption for church-based adoption agencies," she said.
