In a letter to the prime minister, the Lib Dem deputy leader, Vincent Cable, demanded that the government 'take an early initiative to rectify some of the anomalies and abuses which arise from non-domiciled, resident, tax status (sic)'.
The erstwhile economist recommended that 'non-dom status should be time limited' and suggested that 'ten years might be an appropriate dividing line and distinguish those who have settled here from those with temporary residence'.
Dr Cable's remarks follow the proposal by the Conservatives' George Osborne that those enjoying non-domiciled status should be charged an annual flat fee of around £25,000 — a plan that Dr Cable called 'hasty', 'far too optimistic' and 'impractical'.
Last month, the Liberal Democrat deputy leader criticised non-domiciled resident status as an 'expensive gift to the wealthy' and attacked the Treasury for 'suppressing' the findings of a 2002 enquiry into the 'abuses of non-dom status'.
