George Osborne has brushed off the devastating defeat in the Brexit vote and injected a little humour into his Twitter feed.

The Chancellor said fellow cabinet colleague Justine Greening's decision to come out as gay was the “best news in [the] last 48 hours".

He used the social media platform to congratulate the Conservative politician after she revealed the news on the day of the Pride 2016 event.

“Congrats Justine,” he wrote. “Best news in last 48 hours!”

The message was a stark contrast to the preceding messages in his feed, desperately urging people to vote Remain and, later, detailing his reaction to the financial fallout of Brexit.

Justine Greening, Secretary of State for International Development, publically announced her sexuality on social media.

She celebrated Pride by tweeting: “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.”

The Prime Minister also offered his congratulations. In his resignation speech, Mr Cameron said passing legislation approving same-sex marriage was one of the proudest moments of his premiership.

In addition, a number of prominent politicians from across the political spectrum hailed the move.

Pride, which celebrates and promotes LGBT rights, is being celebrated across the UK.
