LONDON (Reuters) - London's top authority said on Wednesday it had referred Prime Minister Boris Johnson to Britain's police watchdog for possible investigation into allegations of misconduct linked to a former US model when he was mayor.

The Greater London Authority said on Friday it had referred Johnson's "conduct of conduct" to the Independent Police Conduct Office, which investigates police-related complaints.

The referral comes after allegations first reported by the Sunday Times that Johnson failed when he was the mayor of London to reveal his close personal relationship with former US model Jennifer Arkory, a technology worker who also received thousands of pounds from public business allowances and on business trips. .

The paper also said that Arkuri had also succeeded in obtaining this year 100,000 pounds (112 thousand euros) of funds allocated to British companies, although it moved to the United States to settle there.

But the latter amount was frozen by a government decision last summer.

"As prime minister of London, the prime minister has done a great deal of work as he markets our capital around the world and promotes London and the UK," Johnson's spokesman told Reuters about the referral.

Arkuri did not immediately respond to a request for comment.

The case was referred to the police oversight body because Johnson was head of the mayor's office of police and crime, a role equivalent to a police commissioner during his tenure as mayor between 2008 and 2016.

In a statement issued by the Greater London Authority, the Supervisory Office of the Greater London Authority recorded a conduct order against Boris Johnson and referred it to the Independent Police Conduct Bureau so that the office could assess whether or not it was necessary to investigate the former London mayor in the offense.
