The mayor of London Matt Brown is temporarily stepping down from his post after admitting to engaging in an “inappropriate” months long affair with Deputy Mayor Maureen Cassidy, who resigned Tuesday evening after apologizing for what she called a brief relationship. Mr. Brown is married with two young children after a radio station heard of the infidelity from several sources at city hall. “Over the past many months, during a period of intense workload, I developed a close working relationship and ultimately an inappropriate personal relationship with Deputy Mayor Maureen Cassidy, for a brief period of time. This was a grave error in judgement on my part. The relationship ended some time ago,” she said.
