Thank you Mrs Grundy have now found it by googling again in greater depth but cannot see why it acquired that meaning from its original use. I learn something with every crossword.
Only have 5 left, all top right, and am totally bamboozled
6a Backing the way Northern Ireland police pressed charges (7) i???b?s
14a Revolts, using force to enter America (9)i?r?s?n?s
All finished but can you please explain why 16a is matelot. I know that's a sailor and can see Ma(?)but can't see "available for hire, has retired" Just seen it!! To let backwards. Tricksy but I am beginning to enjoy cryptics immensely. Thanks for help
