-- Mr Brown later spent more than half an hour at Mrs Duffy's house, apologising to her before telling waiting reporters he had misunderstood what she had said.
He said: "If you like, I'm a penitent sinner. Sometimes you say things you don't mean to say, sometimes you say things by mistake and sometimes when you say things you'll want to correct them very quickly.
"I wanted to come here and say to Gillian that I was sorry, I had made a mistake, but also to say I understood the concerns she was bringing to me and I had simply misunderstood some of the words she had used."
