From daily The Morning Star in Britain:
Hundreds out at first Hanoi Gay Pride parade
Sunday 05 August 2012
Dozens of cyclists decorated with balloons and rainbow flags streamed through the Vietnamese capital Hanoi today for the country’s first-ever gay pride parade.
Organised by the city’s small but growing LGBT community, the event went ahead peacefully with no attempt by police to stop the colourful convoy of about 100 activists despite their lack of official permission.
In a surprise move late last month Justice Minister Ha Hung Cuong said that it might be time to consider a change in the law to recognise same-sex marriage.
Vietnam currently forbids same-sex unions. Any move to legalise gay marriage would make Vietnam the first nation in Asia to do so.
The cyclists voiced strong support for the possible legal changes, calling for equal rights for gays and lesbians.
