Nick Clegg’s speech: Is Leeds Lib Dem?

Refreshing to hear local government namechecked so heaviliy in Clegg’s speech. It does, however, look likes he’s got a little carried away with himself. Clegg said that:

“Our leaders in Sheffield say it could allow the redevelopment of derelict mines in the Don Valley; our leaders in Newcastle believe this could help them create a new science park; in Leeds they argue the Aire Valley could be transformed.”

I’m not sure who this Lib Dem leader is in Leeds. I was under the impression that the council leader was Labour Councillor Keith Wakefield. Shurely shome mistake?
