Some 381 former MP's are in possession of passes that allow them to roam the Westminster estate and use the subsidised facilities. Dozens of former MPs, including Jack Straw and Sir Malcolm Rifkind, ex-ministers under investigation for lobbying allegations, have been granted privileged access to Parliament since the general election. Several ex-MPs who left the House at the 2010 election following the expenses scandal still hold passes.
Questions have been raised about the potential for lobbying of former colleagues and whether individuals should retain access to the estate and take advantage of tax payer subsidised facilities . If you lose your job at McDonalds you cannot pop back for a free Big Mac .
