There has been much debate about the best way to tackle the threat of Nigel Farage to the Conservative Party.
Tory MP Anna Soubry gave it a good go on Thursday night when she appeared alongside the Ukip leader on the BBC's Question Time.
Boston, Lincolnshire, was the venue and many of the audience raised concerns about the scale of immigration. And after an audience member called for a debate based on "facts not fear-mongering", Soubry launched her attack.
"You talk about facts," she said to Farage.
