LONDON: The murdered gay rights activist David Kato had been mocked at a United Nations-backed debate on proposed Ugandan legislation on homosexuality, a US diplomat in Kampala said.

The diplomat said in a leaked embassy cable that in the debate Mr Kato, who was bludgeoned to death near his home in the capital last month, had delivered a well-written speech against a bill that would impose the death penalty for the offence of ''aggravated homosexuality'' and life imprisonment for consenting adults who have gay sex.

However, his words were almost inaudible due to ''his evident nervousness''. Throughout his talk, a member of the Ugandan Human Rights Commission ''openly joked and snickered'' with supporters of the bill, the diplomat said in the cable.

The ''consultative meeting'' in December 2009 was organised with UN funding.
