The reception had a strong sporting theme, with high-profile sportspeople such as Gareth Thomas, Ben Cohen and Billie Jean King attending along with the great and the good from
the LGBT community. Another attendee was Justin Campaign patron and Stonewall FC legend Aslie Pitter.
Jason presented the Prime Minister with a personalised Justin Fashanu All-Stars jersey (above - Jason is in the yellow tie) while he was also photographed with the Parliamentary Under-Secretary for Equalities, Lynne Featherstone MP (below).
In his speech at the event, the Prime Minister admitted that the government needed to do more to encourage lesbian and gay sports people to come out.
The presence of Jason at this auspicious event was yet another truly positive step for The Justin Campaign on the road to beating homophobia in football.
