Actually the man wasn't exactly drowning but "would soon have been in big trouble" and Mr Blair didn't get into the water to rescue him.
No matter. This was a spin doctor's dream come true. Not only was Mr Blair a hero. But had he returned from holiday earlier to ensure his children were back at school on time then clearly a man might have died.
But some elements of the story did lack the heroic touch. Mr Blair had taken to the water because his mobile phone couldn't get a signal on the beach. The holidaymaker did not recognise his rescuer.
But the skipper of the boat, Gerard Muffard, was effusive in his praise. He explained: "Mr Blair called out and asked him if he needed help, and he said `yes'." He added: "Mr Blair was very calm. He just said to him `We can help you. Where do you want us to take you?' We got the dinghy alongside the man and he was able to climb in, but all three of us [including a bodyguard] gave him extra help to get him into the boat."
Police in the Seychelles capital, Victoria, just said an incident occurred and the Prime Minister hauled the man on board. But then police the world over can be jealous of the drama, publicity and awe generated by a true super-hero.
