Reagan wonders if Olof Palme is a communist

[ganzfeld]

From a speech given by Gordon Brown:

I'm reminded of a story that was told of Olof Palme, who was a Social Democratic Prime Minister of Sweden. He toured the world putting the case against global poverty and in the early 1980s, he went to meet Ronald Reagan. Before Olof Palme arrived, Ronald Reagan turned to his advisers and said:

'Isn't this man a Communist?'

And his advisers said: 'No Mr President, he's an anti-Communist'.

And Ronald Reagan said: 'I don't care what kind of Communist he is'.

I heard this on the BBC News this morning so Brown may have told this story more than once or maybe an old tape. This quote seems to be out and about in different froms and from different people but I'm wondering where it came from and if it has ever been verified.
