You couldn’t see it on the telly, but as Clegg shamelessly insisted “only the Liberal Democrats can be trusted” a group of ten or so delegates got up and left. Sorry was not enough for some then…

The line that “to make blue go green you have to add yellow” provoked groans from the press, though there was laughter in the hall.

Clegg’s frankly weird habit of raising his voice at inappropriate moments made the whole thing even more awkward.
