This, of course, is one for the spin doctors. Conventional spin medicine is big on smiles. Every American president since Coolidge has smiled. Mrs Thatcher smiled; even Clement Attlee could look genial. Neil Kinnock stopped smiling, which was a mistake. But you can go too far: Edward Heath. Mr Blair, though, it should be noted, has two smiles. One is a tic, adopted when entering a room or waiting for a question. This, Desmond Morris tells us - and where would we be without Desmond Morris? - is cousin to the grimace of the chimpanzee and indicates non-aggressive intent, a dangerous thing in the Labour Party. The other is a smile of such full-blown, flashing charm that on Panorama last week it lured a hardline law-and-order lady into hoping for a Labour win at the next election.
The message to the medics is clear: cut out the number ones, encourage the telling use of the number two, and let Clause IV look after itself. Meanwhile, another potential problem: yesterday it emerged that Mr Blair's right ear is bigger than his left ear, more pointed, and pinker. He should console himself with Mr Bryce's last verse: 'I like the man who smiles / He seems to be worthwhile / A mirror of eternal good / His smile begets a smile.'Reuse content
