Tom Watson Joins Palantir: What the Appointment Means

Former Labour deputy leader Lord Watson of Wyre Forest has taken a senior vice-president role at US technology firm Palantir. BBC

The appointment was reported on 18 September 2026. Lord Watson announced the move on X, the BBC said.

He will operate alongside Louis Mosley, Palantir's head of UK and Europe. The Guardian Mr Mosley leads the company's UK and Europe operation.

Lord Watson sat as a Labour MP for more than 20 years before leaving the House of Commons and receiving a peerage. He served as deputy leader of the Labour Party.

Palantir builds software to help organisations make better use of their data, a bit like a powerful filing system for complex decisions. In Britain it holds government contracts including with the NHS, the Ministry of Defence and 11 police forces.

The broader context here is why that client list matters. A supplier in health, defence and policing faces close political attention.

Palantir is in a legal battle with the Mayor of London's office over its decision to block the Metropolitan Police from agreeing a contract with the company.

The Mayor's Office said it was not satisfied the deal ensured value for money. It also raised concern about the firm's values. Ministers and officials routinely insist procurement decisions turn on value and suitability. City Hall put both questions at the centre of its objection.

Green MP Sian Berry criticised the appointment as an example of the revolving door between politics and big business lobbying.

The wider pattern at Westminster is familiar. Former ministers and senior opposition figures take private-sector posts. MPs then ask what is being bought: expertise, or access and familiarity.

For those who work around Whitehall, the interest lies less in the job title than in the placement. Palantir is not a conventional lobbyist. It is an existing supplier with live interests across health, defence and policing. Any change in its senior team in London will be read closely by competitors, officials and select committees, the MPs who scrutinise policy.

In my view, two tests will shape how this story develops. The first is transparency about Lord Watson's remit. Working alongside the UK and Europe chief suggests a senior representational brief. Westminster will want to know where advocacy ends and corporate leadership begins. The second is how Palantir handles its dispute with City Hall. A court case over a blocked police contract puts value for money and corporate acceptability in the open. The arrival of a well-known Labour peer invites further scrutiny of those arguments.

For observers, the starting point is straightforward. Peers are entitled to work. Companies are entitled to hire. The question is whether the appointment eases Palantir's path through politically charged procurement decisions, or complicates it by drawing more attention to them.
