MARCH'S INTERRUPTION COEFFICIENTS - THE FULL LIST

*
A new month means another list of interruption coefficients.
*
317 interviews with UK politicians have occured throughout March. This covers every edition of:
*
Today
The Daily Politics
The World At One
PM
The World Tonight
Newsnight
The Andrew Marr Show
Broadcasting House
The Politics Show
The World This Weekend
The Politics Show: Scotland
Dragon's Eye
The Record: Europe
Westminster Hour
*
Just as a reminder - Interruption Coefficients (I.C.s) are calculated by dividing the number of interruptions by the length of the interview. The higher the I.C. the tougher the interview (as a rule). I.C.s of 0 have contained no interruptions! Interruptions are only classed as interruptions if they stop or significantly alter the speaker's flow. Muttered 'wells' and the like are classed as 'abortive interruptions' and are not counted. Those that share an I.C., say of 0.8, are sub-ranked according to a hidden (inferior) measure called the Questions Coefficient, which is calculated by dividing the number of questions by the length of the interview. The more questions there are, the likelier the interviewer is holding the reins in an interview. That means that everything is ranked just where it should be!
*
As usual I will begin with the full list.
*
You will notice something remarkable at the top of this month's list. The Lib Dem-who-loves-to -interrupt found himself last night to be on the receiving end for once. Thus he is March's surprise winner of the coveted Month's Most Interrupted award. *

Every else is pretty much as you expect.
