Two Conservative MPs have been trading blows on the internet with Louise Mensch being labelled "unprofessional and undignified" by Nadine Dorries.
Ms Dorries, who represents Mid Bedfordshire, accused the Corby MP Mrs Mensch of "always putting her own ambitions first".
Mrs Mench responded on Twitter, saying "waking up to find self on the Nadine Dorries naughty step".
Ms Dorries told Susie Fowler-Watt why the two had fallen out.
