Yes, the Phillipine lady is quite attractive.
I don't see how Blair is sexy. That's not me trying to be ultra-hetero; I
can see how Sean Connery or any number of other male movie stars are sexy. I suppose Blair is
relative to other politicians, but that's hardly a compliment, but a can't think of a single male politician anywhere in the last fifty years that would qualify as "sexy" in absolute terms.
I'd say that Blair certainly has charisma, and a modicum of charm.
I'd say Bush has charm, and a modicum of charisma (a subtle distinction). I can even see how some might find him sexy, in a rugged-outdoorsman kind of way (I know he isn't one, but just projects that image a little).
I'd say Reagan had both charm and charisma aplenty, but was not remotely sexy.
Other than this lady, I'd say that the only other world leader there's been in my lifetime that I've ever found sexy would be Benazir Bhutto of Pakistan, during her time as leader there in the 1980s

Fabulous bone structure, smouldering eyes (and fantastically intelligent, which doesn't hurt). Besides which, she was the only female politician under 45 on the world stage at the time. That must have been some kind of advantage - she was competing with Thatcher, for heaven's sake.
Who had huge charisma, but no charm at all. And, apparently, was quite sexy in the flesh (as it were).
I guess here I'm making a distinction between charm and charisma that I should explain. As I've used it here, charm to me means a suggestion that you'd like the person if you met them, even in spite of yourself. Charisma means that you can't help but pay attention to what this person does or says - if there are two people on screen or in a room, you find yourself drawn to watch the one with the most charisma. (As exemplified by Hitler, who I'd say had charisma - you'd watch what he did - but no charm - you didn't find yourslef imagining that he'd be a good person to spend time with.) And sexy is just an indefinable pwhooar factor.
