So who would claim a £1 donation on expenses?

Expense claims rejected by the Scottish Parliament authorities:

• Bill Butler, the Labour MSP for Glasgow Anniesland and a former candidate for deputy leader, listed a £1 claim for a "charity donation".


• Senior Labour MSP, Malcolm Chisholm, tried and failed to get £3 back for a charge on a pay-as-you-go smart card.


• David Whitton, Labour's finance spokesman, who wanted £290 in expenses for printing Christmas cards.


• Alex Fergusson, the Presiding Officer, wanted to recover the £132.78 cost of a "congratulatory advert" for a constituency charity for disadvantaged children.
