Mark Field has been suspended as a minister after pushing a female climate change protester against a pillar and marching her out of an event.

Last night footage emerged of the Foreign Office minister holding a female protester around the neck while walking her out of a Mansion House dinner with Philip Hammond and Mark Carney.

Around 40 Greenpeace protesters gatecrashed the Chancellor's annual address at Mansion House in the City of London and had to be removed by security.

The Foreign Office minister for Asia and the Pacific, can be heard saying: "Can you get this person out?" The woman, wearing a sash reading "climate emergency", replied: "It's a peaceful protest."

Mr Field has reportedly referred himself to the Cabinet Office for investigation and has apologised "unreservedly" to the protester.

A government spokesman said: "Theresa May has seen the footage and found it very concerning.”
