The purpose of the Public Duties Cost Allowance is to assist former Prime Ministers with the costs of continuing to fulfil duties associated with their previous position in public life. Exceptionally, the then Prime Minister agreed that the former Deputy Prime Minister , the Rt Hon Member for Sheffield Hallam, should be able to have access to the allowance to recognise the special position he held in the Coalition Government. Other former Deputy Prime Ministers are not eligible for the allowance. The allowance is set at a maximum limit of £115,000 per annum. The amounts paid are a reimbursement of expenses, accounted for in the published Cabinet Office Annual Reports and Accounts. The former Deputy Prime Minister is eligible for the allowance from the date of leaving ministerial office for the duration of this Parliament.
