The senior civil servant investigates under the authority of the Prime Minister, which complicates her situation, but the lady has already carried out investigations into sensitive cases involving parliamentarians and ministers.
In 2008, she established that Damian Green, a minister of state in the cabinet office who was close to then Prime Minister Theresa May, had lied about the presence of pornographic videos on his office computer.
She is also investigating Liam Fox, Minister of Defense for David Cameron, suspected of not having been able to avoid conflicts of interest in the exercise of his functions.
In 2012, she also conducted the investigation around the “Plebgate”. The case caused a stir when a close friend of David Cameron, Andrew Mitchell, during an altercation with the police who monitor access to 10 Downing Street and prevented him from cycling out the front door , called the agent “pleb”. A contemptuous qualification of the policeman on the basis of his social origin. Despite a public apology, Andrew Mitchell had to resign barely a month after the incident.
