The Prime Minister is to host a reception at 10 Downing St next week to mark LGBT History Month.
Gordon Brown and his wife Sarah will meet organisers and gay equality activists and show support for the event, which promotes equality and combats prejudice faced by the lesbian, gay, bisexual and trans community.
History Month, which takes place throughout February, was started in 2005 by the LGBT campaigning group Schools Out.
It has grown to become one of the biggest events in the LGBT diary, with hundreds of events across the country.
It has been supported by government minister in previous years, but this is the first time the Prime Minister has held a reception for History Month.
The Downing St reception was due to be held this evening but was postponed until next week out of respect for David Cameron, the Leader of the Opposition, whose six-year-old son died earlier today.
