Fresh from his complaint about being snubbed by Gordon Brown, Peter Tatchell is now claiming he was deliberately excluded by Boris Johnson at City Hall's Pride London launch, this week.
Speaking to Pink Paper he said: "Although I am a Patron of Pride London, Mayor Boris Johnson barred me from his Pride launch reception at City Hall on Monday.
"Pride London Chair Paul Birrell twice requested that I and others be sent invites. His requests were ignored. The Pride Committee has confirmed to me that the Mayor's office took over the invite list and ignored its recommendations about who to invite.
"Was I excluded because I recently criticised the Conservatives for joining a right-wing European Parliament grouping that includes the homophobic and anti-Semitic Polish Law and Justice Party?" Tatchell continued.
"Do I care? Not really. I am not campaigning for LGBT human rights to win awards or invites. But I am disturbed that many other Patrons of Pride London and hard working Pride London volunteers were also not invited.
"Tory LGBTs got plenty of invites. Is Boris manipulating the Pride events for party political advantage?" he concluded.
When we asked representatives at City Hall to respond to the claims, they were unable to do so.
