Cotswolds MP Sir Geoffrey Clifton-Brown has been forced to leave the Conservative Party Conference, after what a party spokesman has described as 'totally unacceptable' behaviour towards security staff.
The Senior MP tried to enter the International Lounge on conference grounds with his fiancee - who did not have the right security pass for the area.
When she was denied access, Sir Clifton-Brown reportedly engaged in an argument with security at the door.
Police were called to the area and several parts of the conference venue were put into lockdown - including the press room.
The incident happened not long before Home Secretary Priti Patel delivered her conference speech on the importance of 'law and order'.
A party spokesman has condemned the Cotswolds MP's behaviour, confirming the incident will be investigated.
Following the altercation, Sir Clifton-Brown did not deny an incident taking place.
In a statement, Greater Manchester Police confirmed the disagreement happened after a conference attendee was denied access to the International Lounge because they didn't hold the right security pass.
