More than 50 people will be contacted by the police as part of the investigation into lockdown parties in Downing Street and Whitehall.
The Metropolitan Police says it is pushing ahead with the Partygate probe “at pace” and will send questionnaires about the gatherings to people believed to have taken part by the end of the week.
The questionnaires have formal legal status and must be answered truthfully as part of what the force has dubbed ‘Operation Hillman’.
