Boris Johnson is "unfit for office", former Scottish Conservative leader Ruth Davidson has said.
The Prime Minister has been under mounting pressure in recent weeks over parties held in and around Downing Street during lockdown - one of which he confirmed he attended.
Baroness Davidson, who took her seat in the House of Lords last year after stepping down at Holyrood, was a vocal opponent of the Prime Minister's Tory leadership bid as well as being steadfastly against Brexit - a campaign led by Mr Johnson.
