Nadine Dorries has vowed to 'go after' the Independent Parliamentary Standards Authority after it was revealed an investigation into her expenses claim was launched.
The Independent Parliamentary Standards Authority said they had reason to believe Ms Dorries may have been paid travel and accommodation costs she was not entitled to.
A defiant Ms Dorries vowed to "go after" Ipsa, claiming the expenses body had simply targeted a high-profile MP to justify its funding.
She insisted she was "totally relaxed" about the allegations, saying they were completely unfounded.
They need a high-profile MP to go after to justify their millions in funding. Well I'm going to go after them. All they want to do is get attention to show Ipsa is doing its job.
