UK Prime Minister Boris Johnson on Thursday announced that he will resign as Conservative party leader, BBC reported.
However, Johnson will remain in his position as prime minister until the fall, to allow for a new leadership contest to take place.
The Conservative party will hold elections for a new leader later this summer, BBC added.
Johnson's announcement follows several ministers' resignations: Earlier on Thursday, Northern Ireland Secretary Brandon Lewis resigned, the first Cabinet minister to do so. Following his announcement, several other junior ministers also resigned. They were followed by the UK's newly-appointed Education Secretary Michelle Donelan.
On Wednesday, three parliamentary private secretaries, David Johnston, Claire Coutinho, and Selaine Saxby, tendered their resignations.
On Tuesday, the UK's Finance Minister, Rishi Sunak, and Health Secretary, Sajid Javid, both announced their resignations, saying they had lost confidence in Prime Minister Boris Johnson.
The resignations were part of a campaign to pressure Johnson himself to resign.
