Stop the former PM expense scheme

Not many people are aware that former Prime Ministers can claim up to £115,000 per year of tax payers money under the "former Prime Minister expense scheme".
This needs to be stopped now. Why should hard-working people's taxes be used for this. While we struggle, former PM's are making use of our taxes - taxes which could be put to far better use than lining their pockets.
This scheme should be stopped NOW.
