Lord Darzi’s undeclared interests in four companies included $500,000 of shares in US-based healthcare venture

The independent peer Lord Darzi, a senior adviser to the government on the NHS, failed to officially declare shareholdings in healthcare companies worth hundreds of thousands of pounds.

Ara Darzi is an eminent surgeon and professor at Imperial College London whose report on the NHS for the government in September informed the decision announced last week by the health secretary, Wes Streeting, to abolish NHS England. Darzi also has an extensive portfolio of private interests in commercial medical companies.
