Viewers of last night’s Question Time have condemned the BBC’s decision to allow Charlie Kennedy take part in the programme. The former Lib Dem leader put in a distinctly sub-par performance…

I cannot believe the BBC would allow a completely drunk Charles Kennedy to go on. How sad. #BBBQT

Charles Kennedy… I'm not going to say it, but… #bbcqt

Charles Kennedy not at his best on #bbcqt… Hm.

Does the BBC think it's amusing to have a drunk Charles Kennedy on #bbcqt? Shameful.

Natalie Bennett making about as much sense sober as Charles Kennedy is drunk #bbcqt

As a recovering alcoholic, seeing Charles Kennedy on #bbcqt made me sad. There go I but for the grace of God and all that. Get well soon sir

I’m not sure letting Charles Kennedy on #BBCQT was in anybody’s best interests, to be honest.

Seeing a lot of mocking towards Charles Kennedy.

A good man who needs a little help. Like many people do now and again.

Should the BBC have let him go on?
