Last night I went to the Private View for this year’s Threadneedle Prize at the Mall Galleries, which is worth £10,000 to a winning artist. Thousands of artists submitted artwork and from the work which was selected, and hung for the show, the public can vote for their favourites. The theme this year seemed to be very urban, with lots of gritty landscapes, but there were also some striking portraits and a specially constructed ‘Den’ to go into, which made you feel as though you could be in a hide or disused pillbox near a remote lake.
