Lloyd’s of London is to close its underwriting room — the largest single market place for marine insurance — from 4pm UK time on Thursday.

The move to shut the doors of the iconic One Lime Street building, comes after chief executive John Neal conducted a trial last Friday by closing the room for 24 hours.

The successful completion of the stress test has encouraged Neal and his Lloyd’s executive committee to close the room as the UK’s battle against the spread of coronavirus increasingly concentrates on London.
