BBC: Anti-cuts march: Tens of thousands at London protest
More than 250,000 people attended a march and rally in central London against public spending cuts.
BBC political reporter Brian Wheeler, in central London, said there were lots of families and older people, and the atmosphere was good-natured but the anger was real.
"The noise in Whitehall was deafening as thousands of protesters banged drums, blew whistles and shouted anti-cut slogans, slowly making their way towards Trafalgar Square.
"The crowds were booing as they went past Number 10, but the demonstration was good-natured and friendly.
"There are hundreds of trade union banners, but we have also spoken to public sector workers who have come to make their voices heard."
