Boris in sleaze row over undeclared shareholding

'This calls into question Boris Johnson's competency for one of the most serious jobs in the country' (David Sandison)

Boris Johnson faces the possibility of an inquiry by anti-sleaze watchdogs after failing to declare his shareholding in a television company.

The Labour MP Karen Buck, called on the Parliamentary Standards Commissioner to investigate after it emerged that Mr Johnson did not register shares in Finland Station, for more than 18 months. Aides to the Tory candidate for London mayor said he had not declared his 33 per cent shareholding because of an "oversight" and they had now ensured the shareholding was registered.

Ms Buck said: "Boris Johnson is trying to repackage himself as a serious and competent politician whilst claiming his failure to comply with rules on reporting these shareholdings to the parliamentary commission was simply an oversight. I am afraid this, once again, calls into question Boris Johnson's competency for one of the most serious jobs in the country."

Mr Johnson did declare a £30,000 fee from the company for filming a documentary, The Flame of Rome, which was the only income he had received from Finland Station, his spokeswoman said. "There have been no dividends paid nor are there expected to be in the near future. Finland Station is properly registered with Companies House as is Boris Johnson's interest in that company," the spokeswoman said.

"Although he has received no other income, his shareholding has been registered after this matter was brought to his attention. This is an oversight which Boris Johnson takes ultimate responsibility for."
