"hasn't one" indicates you take an i out of "High above London, Britain" and then it's an anagram - ugly indicates the anagram and Mark Lawrenson is an anagram of "Workman learns". Nice touch from "Paul" the setter to mark our first league game at the Amex - wonder if he's a fan!
I was looking at last Saturday's Guardian Prize Crossword on the train yesterday and came across these two very topical clues!
High above London, Britain hasn't one ugly side (8,3,4,6)
Workman learns about old footballer (4,9)
