British police have been called out to the London home of Conservative leadership candidate Boris Johnson and his partner Carrie Symonds.

The Guardian reported that officers were alerted at 12.24am on Friday, after neighbours said there had been a loud altercation involving screaming, shouting and banging.

Scotland Yard said the caller, who was from south London, "was concerned for the welfare of a female neighbour".

A Metropolitan Police spokesman said: "Police attended and spoke to all occupants of the address, who were all safe and well.

"There were no offences or concerns apparent to the officers and there was no cause for police action."

The neighbour had knocked on the door but received no response, according to The Guardian.

The call came just hours after Mr Johnson was named as one of the two finalists in the race to become the next party leader and British prime minister.
