Ali was a local newspaper reporter and columnist before joining BBC local radio as a producer and presenter, and then chucked in the safe job to be dangerously freelance and write scripts and manuscripts. Her first venture was as a comedy columnist on the BBC Radio's top-rated Woman's Hour and Home Truths programmes. Ali lives in Southampton with her husband and sons and would never kill a creepy-crawly of any kind. They are more scared of her than she is of them. (Creepy-crawlies, not her husband and sons.)
