Yes, Prime Minister1986

Jim Hacker:
You mean the German ambassador's lunch is government business, but mine isn't?

Sir Humphrey Appleby:
That is so. Not just the German ambassador's, of course, any ambassador's.

Jim Hacker:
Fine. Bernard, get the diary. On Monday I'll have lunch with the German ambassador. On Tuesday, with the French ambassador; on Wednesday, with the American ambassador. Oh, mustn't leave out the Commonwealth; on Thursday I'll have lunch with the New Zealand High Commissioner. How many countries are there in the UN?

Bernard Woolley:
Well 158, Prime minister.

Jim Hacker:
Good. That'll take up about six months; then we'll start round again.

Bernard Woolley:
Prime Minister, you're not free to have lunch with ambassadors every day. Sometimes there will be other official lunches.

Jim Hacker:
Even better. We'll fill up the odd gaps.

Sir Humphrey Appleby:
I think that the Foreign and Commonwealth Office might have some views on that.

Jim Hacker:
Oh, why?

Sir Humphrey Appleby:
Well, they always say that one Prime Minister's lunch with an ambassador destroys two years of patient diplomacy. I'm not quite sure how they'd react to 158.
