Thousands of people from across the world are flooding through London's streets on the 43rd annual Pride march through the capital.
Rainbow flags are being flown across a number of city landmarks, with others list up to celebrate the occasion.
Conservative MP and International Development Secretary Justine Greening, also chose today to announce she is in a same sex relationship, 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."

The march will work its way through London's west end, pausing for one minute to commemorate the 49 people who were killed at a gay nightclub in Orlando earlier this month.
A host of musicians and entertainers will address the crowds, as will London mayor Sadiq Khan.
