Supply estimates are the means by which the Government seeks authority from Parliament for its own spending each year. These main estimates start this process and are presented to Parliament around the start of the financial year to which they relate. Detailed departmental estimates are included, and a Supplementary budgetary information publication (Cm. 7359, ISBN 9780101735926) presented alongside provides read-across between the figures in the main estimates and departmental reports. The total resource expenditure for which authority is sought in the 2008-09 main estimates is 447.9 billion, and is consistent with the Government's plans for public expenditure as set out in "Public expenditure: statistical analyses" (HC 489, session 2007-08, ISBN 9780102953770).
