The Health Secretary Andrew Lansley has defended the government's plans to cap the amount of income tax relief on charitable giving.
He told ITV New's Libby Weiner that the Chancellor when he delivered his Budget "very fairly and rightly said" in these circumstances of dealing with the deficit people have to understand that the very richest in society are making a contribution through taxation.
He went on:
"If 10% of the richest people in this country earning income of over £10m a year are paying an effective tax rate below 20% that is not the case. So it is an issue which has to be addressed."
The government appears to have tied itself in knots over the row on charitable giving.
The row over the cap on a tax relief for charitable giving is the latest in a string of rows that have erupted since the budget.
Charities and philanthropists have warned that Government plans to change the way it taxes charitable donations will discourage giving
