Labour is calling for an investigation after claims that the BBC chairman helped Boris Johnson arrange a guarantee on a loan of up to £800,000 weeks before he was recommended for the job by the then-prime minister.
The party has written to Parliamentary Commissioner for Standards Daniel Greenberg following a report in The Sunday Times that Tory donor Richard Sharp was involved in talks about financing Mr Johnson when he found himself in financial difficulty in late 2020.
Mr Sharp introduced multimillionaire Canadian businessman Sam Blyth, who had proposed to act as the then-PM’s guarantor for a credit facility, to the Cabinet Secretary, according to the newspaper.
