Help please, stuck on last two. 9a, Ireland is cleaving Bremner for mocking: i-r-s-r-. Presumably Bremner refers to Rory, but I can only find derisory, which obviously doesn't fit what I've got. Also 20d, Marianne personified as fantastic broad: a model: -a-d-t. I can find the word mandat, paper money issued by the French revolutionary government, but I don't get the rest. Thanks as ever for help.
20 d Bardot
Marianne's features in this century have been modelled on women actors who are considered to be the most beautiful. Brigitte Bardot and Catheine Deneuve were two previous "Mariannes"
