Sir Keir Starmer’s top donor Lord Waheed Alli, pictured at last month’s Labour conference in Liverpool, is being probed by a House of Lords watchdog

Lord Alli has recently found himself at the centre of a ‘freebies’ row engulfing the Prime Minister, pictured in Brussels today, which has dogged Downing Street for weeks

Under parliamentary rules, peers must register all their relevant interests and make sure any change in their relevant interests is registered within one month of the change.

A new listing on the Commissioners’ website today stated: ‘Lord Alli – Alleged non-registration of interests leading to potential breaches of paragraphs 14(a) and 17 of the thirteenth edition of the Code of Conduct for Members of the House of Lords.’

The only other peer listed as being under investigation is Baroness Mone, who has been caught up in a PPE scandal.

It was reported last month by OpenDemocracy how Lord Alli only added his directorship in a British Virgin Islands-based firm to his register of interests after being asked why it was missing.

Lord Alli told the website the omission was an ‘unintentional error’, adding: ‘I hadn’t realised until you asked that it wasn’t listed on my register of interests’.

He now lists his directorship in MAC (BVI) Limited as a ‘non-financial interest’.

Lord Alli is a media tycoon who has been known in political circles for years and donated to Labour for more than two decades.

His donations to senior Labour figures includes £20,000 declared by Sir Keir for accommodation during the general election campaign.

The PM has said this was to allow his son to study for his GCSEs in peace at Lord Alli’s central London flat, while the Starmer’s family home was surrounded by media.

Sir Keir recently defended using a house owned by Lord Alli for a video urging people to work from home during the Covid pandemic.

The PM said the idea it was his home was ‘farcical’, despite there being photos of his family and Christmas cards behind him during the recording, made in December 2021 during the Omicron variant wave.

Instead of it being recorded at Sir Keir’s home in north London, it was filmed at Lord Alli’s flat in Covent Garden, central London.

Sir Keir has said the peer was motivated to help himself and other Cabinet ministers financially because he wanted Labour to win the election.

There is no suggestion that the PM or members of his Cabinet broke any rules in accepting freebies.

But there has been close scrutiny of Lord Alli’s links to Sir Keir after it emerged the Labour peer was given a No10 pass shortly after the party’s election win, despite seemingly not having a Government role.

His pass has since been handed back but Sir Keir has continued to be dogged by the row also dubbed as ‘passes for glasses’.

The PM has since committed to overhauling hospitality rules for ministers to ensure better transparency about what is provided.

Canterbury MP Rosie Duffield cited the freebies row as one of the reasons she resigned the Labour whip on Saturday in protest against the party’s leadership.

A spokesman for the House of Lords said they did not comment on ongoing investigations.

A Labour Party spokesman said: ‘Lord Alli will co-operate fully with the Lords’ commissioner and he is confident all interests have been registered. We cannot comment further while this is ongoing.’
