Mark Field has come under fire after video footage emerged showing him physically removing a female climate change activist from a dinner in the City of London on Thursday.
The Foreign Office minister was seen pushing the activist against a column at Mansion House before holding her by the back of her neck and forcefully walking her out the room.
It came as protesters interrupted a black-tie event where Chancellor Philip Hammond was giving a speech.
Mr Field has referred himself to the Cabinet Office for investigation and has apologised "unreservedly" to the activist, while Conservative Party chairman Brandon Lewis said the party will investigate.
Here’s everything you need to know about Mr Field:
Mr Field, 54, has held a number of ministerial roles since being elected as the MP for Cities of London and Westminster in 2001.
After joining the Tory frontbench two years after first winning a seat in the Commons, taking the role of Opposition Whip, he was later appointed shadow minister for London.
Other roles such as shadow financial secretary to the Treasury and shadow minister for culture and the arts followed, but it was after the 2017 election that he took one of his most prominent positions as minister of state for Asia and the Pacific at the Foreign Office.
In that role, Mr Field has spoken out on issues such as Britain's interventions in Iraq and Libya, the collapse of an international nuclear treaty and the plight of the Muslim Rohingya in Burma.
Most recently, he spoke in the Commons about Hong Kong's controversial extradition bill, warning that it could have a "chilling effect" on rights and freedoms.
According to his official website, Mr Field has a particular interest in British relations with China and Russia.
The 54-year-old, born in Germany in October 1964, was educated at Reading School and later completed a degree in law at Oxford.
He practised as a solicitor before his political career began and was an elected councillor in the Royal Borough of Kensington and Chelsea.
In September 2010, Mr Field became the youngest MP on the Intelligence and Security Committee, which oversees the work of Britain's intelligence services, and he was later made a Privy Counsellor in recognition of his work on the committee.
He has also served as vice chairman (International) of the Conservative Party.
A father-of-two, he lives in Westminster with his wife Vicki, son Frederick, born in 2007, and daughter Arabella, born in 2011.
His website lists his interests as urban walking, pop music and researching local London history, and he is also said to be a lifelong sports fan.
