In the UK, you can only use reasonable force to remove someone if you believe them to be a threat to other people or property. This applies to the police as well.

Police cannot remove you from a property on a trespass charge as it is a civil, not criminal matter (UK). Instead they will use a public order charge, even if it means escalting the confrontation a bit to make it appear relevant.
