• Expect people to be out and about around London at all hours this weekend with the kick-off tonight of Museums At Night, Culture24’s annual festival of after hours visits. This year’s packed program features everything from ‘Arts on Ice’ – a look at the Victorian ice trade – at the London Canal Museum to art nights at the Government Art Collection building, nocturnal tours of Greenwich’s Old Royal Naval College, and, for the first time, the chance for adults to sleep over at Hampton Court Palace and kids at Kensington Palace. Other London organisations taking part include the Handel House Museum, the Kew Bridge Steam Museum, Benjamin Franklin House, the National Gallery and Somerset House (and that’s just a few off the list!). For more information on the night – including a full program of events – check out the Culture24 Museums at Night website.

• Government spin comes under the spotlight in a major new exhibition which opens tomorrow at the British Library in King’s Cross. Propaganda: Power and Persuasion examines how state have used propaganda in the 20th and 21st centuries and features more than 200 exhibits including Nazi propaganda and everyday objects such as banknotes and badges.

• It’s 10 years since the Museum of London Docklands opened in a converted Georgian warehouse on West India Quay and to celebrate they’re holding an exhibition celebrating the Thames estuary. Titled (appropriately enough), Estuary, the exhibition features the work of 12 artists in a variety of mediums – from film and photography to painting. Entry is free. The exhibition, which opens tomorrow, runs until 27 October. The museum is also holding a special day of family activities to celebrate its creation this Saturday. For more, see www.museumoflondon.org.uk/Docklands/.
