 In the aftermath of the Derek Conway scandal over the misuse of funding for political researchers, the TPA has called for greatly increased transparency, improved scrutiny of expenses and the abolition of some expenses such as the allowance for MPs' second homes.The Alliance has also written to the Parliamentary Standards Commissioner to request an investigation into the expenses of Michael Martin, the then Speaker of the House of Commons.They have not, however, argued for commensurate levels of accountability from pressure groups that receive commercial funding, and critics have argued that they are in favour of transparency only from people who are elected, as opposed to transparency for organisations that conduct political campaigning for commercial ends.
