A well-known London lawyer has “unreservedly apologised” but insisted he has “legitimate concerns”, after tearing posters off the walls of a Liberal Democrat parliamentary candidate’s office and launching into an angry rant about her.

Police were called to the office of Liberal Democrat parliamentary candidate Luciana Berger on Friday after former SJ Berwin partner Jonathan Metliss stormed into her office and began shouting abuse about her, according to the Jewish Chronicle.
