Having watched the footage from the hall again, I think two incidents might be conflated here. Simon McGrath's speech made the point that the FCC had over-ruled the police, insured people have to act prudently, and amendment 2 was dishonest. If there was heckling, it wasn't heard on the broadcast.

Geoff Payne, summarising for Amendment 1, was interrupted by shouts from the floor, both when he said that "conference is the same as it always was" and that "we agreed a system with DELGA for trans people".

For the benefit of Mr. Payne, and previous speaker Chris White, this blogger has declined to attend the present conference, precisely because of the vetting process in operation. From the tenor of their speeches, it's evident my insights and experience are not of any value to the party.
