London Mayor Matt Brown has separated from his wife, Andrea, CBC News has learned.

The separation comes a little more than three months after Brown admitted to having an affair with city Coun. Maureen Cassidy, who was deputy mayor at the time.

Several CBC sources confirmed the separation. Officials from the mayor's office declined to comment.

When the news about the affair broke in June, Brown issued a statement saying his inappropriate relationship with Cassidy was a grave error in judgement on his part.

He also said it had put a tremendous strain on the relationship with his wife. But Brown said he was committed to repairing the damage.

Andrea Brown issued her own statement at the time, saying that she, too, was committed to saving the marriage.
