Gordon Brown has condemned California's ban on gay marriage as "unacceptable" and warned people to be vigilant against all forms of discrimination...
Mr Brown said "this attempt to undo good that has been done is unacceptable".
He added: "This shows why we have always got to be vigilant, always got to fight homophobic behaviour and any form of discrimination."
He also praised equality campaigners in the UK for "changing opinion" about same-sex unions.
I hope Obama will be the American leader who firmly stands up for equal rights. There's a long way to go, but then again, it wasn't until Obama was elected that you could even imagine a US president saying something like "our gay and lesbian brothers and sisters."
