After being forced to resign in 2014 Hill later did a stint with lobbying firm Lexington Communications until she was reappointed by Theresa May in July 2016.
Originally a press officer for shadow health secretary Andrew Lansley, Cunningham left her role at the Conservative Party to join business lobbyists the British Chambers of Commerce in June 2008. She returned to the Conservatives in March 2009 after less than a year in her previous role. According to Conservative media adviser Henry Macrory, 'She couldn’t keep away".
Hill lost her job as May's special adviser as part of the fallout over the Cabinet's 'very ugly public feud' about an alleged 'Trojan Horse' plot to Islamicise secular state schools in Birmingham, widely believed to be a hoax.
She was found to be 'the source of an acidic briefing' against education minister Michael Gove. Gove had briefed The Times newspaper — as an anonymous "source" — over the alleged plot and had accused the Home Office of failing to “drain the swamp” of extremists and criticised Charles Farr, Theresa May’s counter-terrorism adviser, who was reportedly in a relationship with Hill. 
Hill's reappointment in July 2016 as the newly appointed prime minister Theresa May's chief co-adviser alongside Nick Timothy was similarly beset by controversy. The two special advisers immediately stood down after May's 2017 election campaign resulted in the first Conservative minority government in decades.
Ignored ACOBA rules
After leaving the home office, Hill took up a lobbying role with Lexington Communications in 2015 without informing the Advisory Committee on Business Appointments (ACOBA), which scrutinises moves from Whitehall to the private sector for potential conflict of interests.
Once it was revealed Hill had failed to follow proper procedure, the government changed ACOBA's rules to exempt all special advisers and political aides from needing to apply for approval when taking up a role outside of government.
Tamasin Cave, of Spinwatch, said of the development:
- 'The contempt she [Hill] has shown for the rules is supportive of a culture in Westminster and Whitehall that sees trading insider knowledge as routine.’
