Video: David Cameron 'committed to ending tax abuse' The Prime Minister hinted that proposed changes to donation rules could be focused on gifts to non-British charities. Ministers say the change is needed because some rich people are abusing the relief to cut their income tax bill. Charities have said the move will deprive good causes of significant donations. Speaking in Jakarta, Mr Cameron said the principle of tightening up on tax relief was sound, because "there is no doubt that abuse is taking place." He said: "We're very clearly informed of that, by the Inland Revenue, some people have been using charities established in other countries to funnel money in and get their tax rates so they're not paying 50p tax or even 45p tax but in some cases are paying 10 or 20 per cent tax, and I think that isn't right."
