British Government minister Justine Greening has come out, revealing that she is in a same-sex relationship.

In doing so, the Putney MP and International Development Secretary, becomes the first out LGB female cabinet minister.

She tweeted her announcement, writing: “Today’s a good day to say I’m in a happy same sex relationship, I campaigned for Stronger In but sometimes you’re better off out!#Pride2016”
