[Better late than never.]
From: The Wedding Party (the third episode of the first series, broadcast 3 October, 1975)
Sybil: Tell them you made a mistake.
Basil: Oh, brilliant. Is that what made Britain great? "I'm so sorry I made a mistake". What have you got for a brain - spongecake?
And while we're on the topic of Australian politics, here's what Basil has to say about women a little later in the same episode. I find it's a little bit more amusing if I insert the words Julia Gillard and Kristina Keneally where he refers to "women" and "my wife". I'm so easily amused.
Basil: I'm sorry... I'm so sorry, but my wife has made a mistake, I don't know how she did it, but she did, she's made a complete pudding of the whole thing as usual, it'll be perfectly all right for you to stay. I've sorted it all out, I'm frightfully sorry but you know what women are like, they've only got one brain between the lot of them, well not all of them but some of them have, particularly my wife...
