Didn't make much progress so headed to 225 for enlightenment.
Still don't get
10a Renegade filibuster stripped of his external prize (3)
Ans rat given as [pi]rat[e] (filibuster, stripped of his external pie (prize))
I thought a filibuster was speaking at length to time out proposed legislation but leaving that aside , how does pie=prize?
20d 20. Fanciful charge for peeping Lords, at least (7) Ans given as
peerage -cryptic definition. I think the first bit refers to putting age on a wrod to mean the cost of e,g cartage. Lords are peers but where does "at least" fit in?
