Disaffected multinationals were urged on Thursday to spell out their concerns to the Treasury, after signs that some businesses are still considering leaving Britain in spite of this week’s concessions over the international tax regime.

The plea for greater dialogue was made by a senior Treasury official following a straw poll of 70 businesses suggesting that some remain frustrated by the government’s approach. About 9 per cent said they were more inclined to emigrate from the UK after the Treasury explained its current stance on taxing foreign profits.
