Protesters took part in a national day of action over planned library closures yesterday and today by staging all-night sit-ins.

Campaigners worried about their library's future took part in a "read-in" at several libraries across south London, with some vowing not to leave until lunchtime on today.

The protests have also been taking place at dozens of threatened libraries across the UK , with Philip Pullman and Mark Haddon among a number of authors taking part.

York Gardens library in Battersea saw dozens of people join its read-in protest yesterday afternoon, and were supported by Polly Toynbee, a star columnist for The Guardian newspaper.

Campaigner Thea Sherer said: "York Gardens Library serves the poorest ward in Wandsworth – and yet is the only library the council plans to shut.

"We're trying to show them today that if they thought people in this area would just roll over and take it, they misjudged."

In Norbury library, actor Ralph Ineson (who starred in a Harry Potter movie and BBC comedy The Office) tried his hand at storytelling as part of the anti-closure protests.

And at Brixton library campaign group Save Lambeth Libraries were joined by the UNISON union to protest about the cuts.

More than 450 libraries and mobile services across the country are currently threatened with closure.
