A Welsh MP has been interviewed by police over allegations of a fraudulent expenses claim.
Chris Davies, Conservative MP for Brecon and Radnorshire, was referred to police by the Independent Parliamentary Standards Authority (IPSA).
It is alleged he made a false expense claim for pictures used in his constituency office in 2016.
He has previously said he made an "honest mistake" and voluntarily spoke to the Metropolitan Police.
A Scotland Yard spokesman said inquiries were continuing.
"A 50-year-old man was voluntarily interviewed under caution on Tuesday, 17 July 2018," he added.
It is understood Mr Davies is accused of manually creating two invoices for £450 and £250 rather than submitting the full £700 claim for the pictures by computer.
He has previously said that he repaid the £450 sum, which was charged to a start-up fund for new MPs to set up offices.
Mr Davies was referred to IPSA in April 2018 and compliance officer Andy McDonald passed on the claim to the Metropolitan Police.
