Mid-Bedfordshire MP Nadine Dorries is facing an investigation into her expenses claim by a parliamentary watchdog.
The Independent Parliamentary Standards Authority's Peter Davis said he had reason to believe Ms Dorries may have been paid travel and accommodation costs she was not entitled to.
"An investigation will be conducted into claims submitted under the following areas of the third and fourth editions of the MPs' scheme of business costs and expense - accommodation expenditure, travel and subsistence," he said in a statement.
