It really seriously pisses me off that when politicians are asked a yes/no question that they just make a random comment, peppered with "and this is important" to stop their interviewers interrupting.
They should be told "it's yes or no and if you refuse to respond then we will announce your job is vacant for someone who will respond."
"Well I think the important thing.."
"Viewers, Diane Abbott has now resigned. Goodbye Miss Abbott. And in other news..."
