The rainbow flag is being flown over Whitehall until Monday, in celebration of the first same-sex marriages which will take place from tomorrow.
Mr Clegg said: “Raising the rainbow flag on Whitehall is a small symbol to celebrate a massive achievement. I want to wish everyone getting married this weekend the very best of luck, on what is a truly momentous occasion.”
