The leader's speech is a traditional conference set piece which should inspire the troops and win good publicity. The LibDem chief has, I'm told, failed on both counts. The BBC is leading on his claim that he isn't too old to lead the party and says that with age comes experience and judgement.
Sir Ming was wrong to do this - by even including it in the speech he has skewed his own media story. This is probably the one speech that will definitely get coverage and to waste it by fueling the leadership story is a classic example of his lack of judgement.
Added to his tax-the-rich call, his EU referendum u-turn and his closeness to Brown you have to wonder if he has any judgement at all.
