Former defence secretary Liam Fox successfully claimed 3p of taxpayers' cash for a car journey of fewer than 100 metres, expenses documents show.
The Conservative MP made the claim after travelling 0.06 miles, or approximately 96.5 metres, within his North Somerset constituency from a concrete firm to a constituency surgery in Yatton in October 2012.
The Independent Parliamentary Standards Authority (Ipsa) notes the claim was paid last December.
Mr Fox also had another 15 claims of under £1 for car travel approved in 2012/13.
Scotland Yard has said it plans to reopen the investigation into the former Labour MP Denis MacShane's expenses.
A spokesman said: "We can confirm that following an assessment of the report published by the Standards and Privileges Committee and following liaison with the Crown Prosecution Service, the Metropolitan Police is reopening the investigation."
The expenses investigation facing Maria Miller follows a complaint that she claimed more than £90,000 in second home allowances towards the cost of a house where her parents lived.
The complaint was lodged earlier this week by Labour MP John Mann, who claimed the arrangement was "identical" to that of former Labour minister Tony McNulty.
Mr McNulty was required to pay back more than £13,000 in expenses two years ago, after being found to have effectively "subsidised" his parents from the public purse by allowing them to live rent free in a second home.
Earlier this week Mrs Miller insisted that all of her expenses were "absolutely as they should be" in response to an article in The Daily Telegraph that reported the claims.
The former Labour MP Margaret Moran claimed nearly her entire annual allowance in one bogus expense entry, a jury at Southwark Crown Court heard today.
The former MP for Luton South submitted an invoice for £22,500 in August 2008 - just under the annual allowance - to treat dry rot at her Southampton home but instead used the money to fund "home improvements", the court heard.
She is accused of falsely claiming around £60,000 in parliamentary expenses between 2004 and 2008.
