Palantir's Tom Watson accuses MP of inaccuracy while citing NHS data without caveats

Palantir's new UK senior VP Tom Watson accused Labour MP Clive Lewis of making "incorrect claims" about the company. His letter cited NHS Federated Data Platform figures showing benefits at 137 trusts, omitting the statistics regulator's caveat that cause and effect cannot be established.

• Watson said the NHS FDP is live at 142 trusts and 137 report benefits
• The OSR told NHS England to communicate those figures more carefully
• Foxglove: 13 of 41 trusts using the tool reported fewer operations
• One trust accounted for 84% of the reported fall in waiting lists
