Eddie Mair is my favourite. He regularly stilettos people on Radio 4's PM, but he's so subtle that some don't notice until they take look down and see all the blood on their shirt. His most high profile monstering was of Boris Johnson, who seemed to walk into him expecting the usual easy ride...
I liked how agitated Holmes got when Corbyn said that leading a political party was not like managing a football team. EH must have been thinking 'If people start to realise that not every topic can be discussed using an analogy involving Alex Ferguson, my career will be over!'
