Adam Lambert, Keegan Hirst and Ireland's gay marriage vote were among the winners at Thursday's Attitude Awards 2015 in London.

Attitude, the British LGBT lifestyle magazine, presented its Ally Award to Reggie Yates for his BBC documentary Extreme Russia, which exposed the discrimination and violence LGBT people face in the former Soviet Union.

Singer Adam Lambert performed at the event and walked away with this year's Music Award/International Album.

Ireland's yes vote for marriage equality was named the greatest moment of the year.

Attitude gave its Actor of the Year Award to Cyril Nri, who stars on the Channel 4 series Cucumber, and named television presenter Evan Davis its man of the year.

The Editor's Special Award went to rugby player Keegan Hirst, who came out gay in August.
