How much does your MP earn, on top of their salary, and where does the money come from?For years, many stories have come out of Westminster that have seen MPs wrestling with money - the expenses scandal, cash for questions, the Owen Paterson saga - and time after time, politicians have promised to make changes.But a Sky News investigation with Tortoise Media has pulled together the details of the money that is still flowing around politics, with MPs making £17.1m on top of their salaries in this parliament (i.e. since 2019). Around two-thirds of that money has gone to just 20 MPs.On this edition of the Sophy Ridge on Sunday podcast, our deputy political editor Sam Coates joins Sophy and show editor Scott Beasley to talk through the Westminster Accounts project, and why it matters.Elsewhere, with Labour continuing to hold a lead in the polls, the party's leader Sir Keir Starmer sits down with Sophy for his first big interview of 2023, outlining his plans for the country, should he win the next election.Plus, both he and Health Minister, Maria Caulfield, give their first responses to the Westminster Accounts project.You can search The Westminster Accounts for your MP by clicking here.Producer: David ChipakupakuEditor: Paul Stanworth
