I can't get this one: 15d First lady's one afloat unceasingly (4.5) ?V?R/???E? The Week puzzle is set by Tim Moorey, who does the Sunday Times crossword regularly. He combines elegant, clever clues with ones that are impossible to solve from the clue, so you have to guess the answer and then work back.
Well done scorpiojo. Now I shall be in with a chance of winning the prize, which is "a bundle of Week goodies", including a copy of "How to be Really Well-informed in Minutes"!
