Christopher Davies, MP for Brecon and Radnorshire, admitted to submitting expenses claims, which he knew to be “false or misleading”, at Westminster Magistrates Court on 22 March.
The charges are the first of their kind under the Parliamentary Standards Act, which was created following widespread findings of expenses fraud by several MPs in 2009.
Davies admitted to one charge of providing false or misleading information for allowances claims and one charge for attempting to do so, it has been reported.
The claims related to photographs used to decorate his constituency office, following the 2015 general election.
Davies split a £700 bill between two fake invoices and charged them to two separate budgets available to him as an MP.
He has since repaid one of the invoices worth £450 , while the other invoice, worth £250, was never submitted.
Ian Lavery, Labour Party chairman, said: “Trust in politics and politicians is essential to our democracy. Chris Davies cannot remain a Tory MP after admitting this offence.”
Davies was charged in February this year.
