4.22pm: McMullan says he regrets the stories he did on Jennifer Elliott, the daughter of actor Denholm Elliott.
She became a drug user and started begging following the death of her father and the News of the World exposed this.
I really regret it because I'd got to know her very well and I really quite liked her. The fact she was begging outside Chalk Farm station came from a police officer, who had been surprised when he asked her to move on.
I went too far on that story. Someone crying out for help, not crying out for a News of the World reporter.
I then took her back to her flat and took a load of pictures of her topless.
Then she went on TV and described me as her boyfriend.
He adds:
When I heard a few years later that she'd killed herself I thought 'Yeah that's one I really regret.' But there's not many.
Sometimes I wouldn't have bought the News of the World even though I worked for it, but the British public carried on.
