Hundreds of thousands of gays, lesbians and their supporters on Saturday took part in a colourful parade across Madrid, the capital of a country that has become a world leader in gay rights.

Equality Minister Bibiano Aido led the parade of more than 30 floats, mostly related to gay bars and other businesses, but also one devoted to the Abba-themed musical "Mamma Mia", under a hot sun and to the beat of techno and Brazilian music.
