Britain's three main party leaders, David Cameron, Nick Clegg and Ed Miliband, have all promised to leave a tenth of their wealth to charity when they die.
The politicians are donating the money as part of a new drive to get British people to leave more money to good causes in their wills.
The government will waive inheritance tax on charitable donations in wills at a cost of around £300 million ($462 million) per year from this April, which it hopes will spark a new trend toward philanthropy.
