McNulty's tenure at Surrey County Council included various controversies, including over his large salary and expenses package, leading to a petition calling for the Council to abolish the £220,295-a-year role to cut costs.
He was further criticised for being on annual leave while the Council debated a 4.99% rise in council tax, during which text messages between Council Leader David Hodge and an official from the Department of Communities and Local Government were raised by Labour Leader Jeremy Corbyn to Theresa May during Prime Minister's Questions on Wednesday 8 February 2017.
