“Let’s be clear: these allegations are smears from former staff who I sacked after they were accused of bullying behaviour, lying about other colleagues to cover up their own failures and general gross incompetence,” Ms Badenoch wrote on X, formerly Twitter.

“Intolerable behaviour I would not stand for,” she added.

The Tory former minister, among those running to be the party’s next leader, also claimed the Department of Business and Trade had confirmed there were no complaints and no investigations against her.

She said the accusations would not “stop me or my campaign” and claimed her bid to be the next Conservative leader following the party’s general election rout had “spooked the lefties and now they’re coming for the one person they know can beat Keir Starmer”.

Ms Badenoch, the MP for North West Essex, added: “The renewal of my party and the country is too important to let the Guardian, acting for the Labour Party, disrupt.”

The Guardian article claimed Ms Badenoch was responsible for behaviour that traumatised staff, leading at least three of them to leave their jobs at the Government department.
