It was 47 years ago today...

...that Prime Minister Harold Holt disappeared while swimming at Cheviot Beach, Portsea, 59 miles from Melbourne.

Dig that nifty little wetsuit! PM Harold Holt with his step-daughters-in-law, Amanda, Caroline and Paulette. 

Holt's body was never found, giving rise to all sorts of conspiracy theories: such as the one that he'd been kidnapped by communists and whisked away in a submarine, or that he faked his own death so he could run off with a secret mistress.

Groovy bikinis too.

Suffice it to say, I can think of one or two pollies today who are far more deserving than Holt of such a fate...
