International Development Secretary Justine Greening has used pride day to announce she is in a same sex relationship.
The Cabinet minister insisted it was a "good day" to speak about her private life.
The former transport secretary has been MP for Putney in London since 2005.
Greening, 47, follows Scottish Secretary David Mundell who came out as gay in January when he announced on his website it was time to "acknowledge in public, as well as in private, who I am".
Chancellor George Osborne congratulated Greening on Twitter and made an oblique reference to the referendum result.
Leader of the Scottish Conservatives Ruth Davidson, the first openly gay head of a major political party in the UK, was also very pleased.
As too was Prime Minister David Cameron.
