Former Scotland Yard counter-terrorism chief John Yates attended the wedding of the News of the World's ex-crime editor, the Leveson Inquiry heard today.
Journalist Lucy Panton said Mr Yates was just one of "many" police officers of all ranks who were guests when she married a Scotland Yard detective.
She told the inquiry: "There were a few people at my wedding who I would class as working friends, who I didn't socialise with outside of work.
"Mr Yates falls into that category. I certainly got on well with him. I had a good rapport with him.
"But we didn't socialise outside of work. The wedding was the only occasion."
Ms Panton added that Mr Yates attended the wedding of fellow crime reporter Jeff Edwards, who worked for the Daily Mirror from 1992 until he retired in 2008.
