The new £10 is the second plastic or polymer note issued by the Bank of England and features a portrait of Jane Austen. It follows the introduction of the first polymer note in September 2016, a fiver with a picture of Winston Churchill and an extract from his famous speech: ‘I have nothing to offer but blood, sweat, tears and toil.’ The new twenty-pound note, with a portrait of a young J. M. W. Turner and a version of his painting of the Fighting Temeraire in the background will be released in March 2020. As yet no decision on a polymer fifty-pound note has been made and who would feature on it.

It's got to be one of London's best-loved events: from the arrival of the eagerly awaited annual catalogue and the feverish planning of visits, to that autumn weekend when the city flings open its doors to citizens and visitors. Yup, it's Open House - time for Londoners to get up close and personal with buildings they normally can't access.
