HOW THINGS STAND

*
I think it's time to work out another super(duper)-average - i.e. the average I.C. for each political party since I began recording interruption coefficients last June.
*
So far 2194 interviews have been monitored.
*
The bias against right-of-centre parties (and nationalists) remains clear and unequivocal:

UKIP (30) - 1.01
Conservatives (619) - 0.85
English Democrats (1) - 0.80
SNP (70) - 0.76
Sinn Fein (9) - 0.71
BNP (4) - 0.65
Plaid Cymru (11) - 0.65
DUP (10) - 0.62
Labour (1054) - 0.59
Liberal Democrats (333) - 0.44
Greens (16) - 0.26
TUV (2) 0.25
SDLP (3) - 0.20
UUP (2) - 0.15
Alliance (6) - 0.03
Respect (1) - 0

So, a UKIP spokesman is four times more likely to be interrupted by a BBC interviewer than a Green. A Conservative is twice as likely to be interrupted by a BBC interviewer than a Lib Dem. Labour - the government of the country! - is questioned less toughly than Plaid Cymru.
