Labour donor Lord Alli breached four parliamentary rules over his registration of interests, a standards watchdog has found.

Sir Keir Starmer’s largest donor was found to have failed to include all his roles at a charity, did not register he had a controlling interest in a media company and did not register he was a director of a British Virgin Islands’ based firm in time.

This is unrelated to questions over the way in which he donated to politicians such as the prime minister and other ministers.

Lord Alli, a TV executive, was recommended to write a letter of apology to the chair of the Lords’ conduct committee, Baroness Manningham-Buller.

In his letter, he wrote: “I am writing to you today to offer my apology for my breach of conduct by not registering my interests correctly.

“I will endeavour to keep to the Code of Conduct at all times to avoid such circumstances again.”

The first breach said Lord Alli should have registered himself as an unremunerated director of The Charlie Parsons Foundation, as well as a trustee.

He helped set up the charity in 2011 with Charlie Parsons, who created the Survivor reality TV series, to invest in “new talent, new projects and new business ideas”, mainly in the TV and entertainment industry.
