Downing Street have now said they will confirm whether Cabinet secretary Simon Case is fined by the Metropolitan Police.
It previously said it would only announce a fine received by Boris Johnson and that other officials and special advisers will not be named.
But Mr Johnson’s spokesman said they would clarify the situation regarding Mr Case, given his “unique position”.
It comes after Downing Street earlier refused to say if Boris Johnson will resign if he is fined over lockdown-breaching parties at No 10 after the police announced it is issuing fines for 20 cases of lockdown breaches.
Mr Johnson has not yet been informed whether he will receive a fine, his official spokesperson said but added that they are “committed” to ensuring the public is informed if the prime minister is given a penalty notice.
Twelve events across Downing Street and Whitehall are being investigated between May 2020 and April 2021, six of which the prime minister is alleged to have attended.
