But you said that they made no mention of it being his last show when they did.
Now you are moving the goalposts when someone points they did .
Apparently you just wanted to criticise the BBC for no reason .
I didn't see them mention it on the news, if they did then I stand corrected. However, all I heard was the announcer mention it as he introduced the programme. To the best of my knowledge it was not mentioned in the news itself.
