I've solved about a third so far but it's where to put them that's causing a real headache! Even if they fit they might one of the five answers that need to be replaced - this is going to take some careful working out.
In the Gilbert clue, I can’t see the relevance of “take on board” in the wordplay. I need it to equal X to fit in with my answer.
Any help much appreciated as I am making very slow progress with only two answers entered.
