What was the name of show (and the man who hosted it) about the english language?

It was on about 18 months, 2 years ago, think it was by the BBC. It wasn't as popular as QI etc but was along them lines. It was a quiz show on the english language and they had fairly famous people taking part. One of the rounds they ysed sentences for grammatical errors/spelling mistakes etc. The man who hosted it has quite a posh accent, in his 50's (possibly older), short hair. Does anyone know what he is called?
