Does it matter if politicians have 'non-dom' tax status?
The Electoral Commission has said £5.1m of donations to the Tories from a firm belonging to Lord Ashcroft were legal. Who should be allowed to donate to political parties?
Firms must be "carrying on business in the UK" to be allowed to donate money to British political parties. Following a 14-month investigation the commission found that donations by Bearwood Corporate Services were "legal and permissible".
Meanwhile the Conservatives say party leader David Cameron was only told last month about Lord Ashcroft's tax status, after the peer admitted on Monday that he does not pay UK tax on his overseas earnings.
Who should be allowed to donate to British political parties? Should there be a limit on donations? Does it matter if significant figures in political parties are "non-domiciled"? Will tax status be an election issue?
