London Connection Puzzle
This week's puzzle is set by Dave Brown, winner of last week's competition. He's sent in four clue-words with a London connection, and we'll publish one each day until someone works out the theme. So, your first clue-word of the week is DONALD. Another one tomorrow.

London Weather, by Inclement Atlee
'Pleasantly warm', says the BBC forecast. But beware. The weather in this city can change on a sixpence. For example, tweak just two letters, and 'pleasantly warm' becomes 'pheasantly wart', and nobody wants one of those. A 'generally sunny start' will become a 'generally funny tart' by midday, and that 'occluded front moving in from the west' will transform into a 'deluded frog removing its vest' by evening. In summary: slightly malapropy.
