British Prime Minister Boris Johnson has unpaid debt worth £535

British Prime Minister Boris Johnson, whose personal finances have come under the spotlight over the renovation of his Downing Street apartment, has an unpaid debt of 535 pounds ($756.12) court records showed on Wednesday.

The court judgement seen by Reuters did not name the other party in the case, but listed Boris Johnson and the address of his 10 Downing Street office.

The record was dated October 26 2020, and listed as 'Unsatisfied' meaning it was wholly or partly unpaid. It was first reported in the "Private Eye" magazine.

A spokesman for Johnson said his Downing Street office was "looking into this issue".

"I can confirm it is nothing to do with the refurbishment of the Downing Street estate where all such bills have been duly paid either by the government or by the prime minister personally," he said.

When asked whether there should be concerns over Johnson's finances, the prime minister's press secretary said: "You should not be concerned, no."

Johnson's finances have been the subject of extensive scrutiny in recent weeks, with electoral authorities investigating the funding of a refurbishment of his flat, and parliament investigating the declaration he made relating to a donor-funded foreign trip.

A county court judgement is issued when someone submits a claim and judges decide the money needs to be paid. The register of these judgements is used by banks and other financial institutions to determine an individual's credit rating.
