From Lord Balfour.

Sir, Drafting new tax rules for those classed as “non-doms” (UK resident but not domiciled) is proving hard. An important core of people (many in the financial sector, which Gordon Brown recognises as vital to the UK economy) is already contributing very substantially to the Treasury via pay-as-you-earn and National Insurance. Their often foreign employers, who could move offices and employees abroad, are paying large amounts of corporation tax.
