Officials who will be mentioned in Sue Gray’s impending report on Downing Street lockdown gatherings have until 17:00 BST to object.

Ms Gray, the investigation’s lead investigator, is set to release her full findings in the coming days.

Ms Gray has “full control” over the details she reveals, according to Education Secretary Nadhim Zahawi.

However, Labour asked that the study be made public “in its whole and with all supporting documentation.”

Whitehall sources told that challenges from persons who are expected to be identified; those persons could still be filed before the deadline, postponing publication.

However, as of Saturday, no challenge has been launched.

A separate Metropolitan Police investigation into lockdown gatherings finished this week, with 126 penalties handed to 83 people, including one to Prime Minister Boris Johnson.
