Senior Cabinet Office director Anand Aithal has non-dom status

Revelation is likely to lead to further questions about the criteria for holding the favourable tax status

One of the most senior Cabinet Office directors is a non-dom, the Guardian can reveal, in a disclosure which comes as Labour vowed to crack down on the favourable tax status.

Anand Aithal, a former Goldman Sachs managing director, is the lead non-executive director at the Cabinet Office, a role which a Whitehall source said meant he had significant responsibilities in the department and a close relationship with the Downing Street chief of staff, Steve Barclay.
