The above pie charts represent the proportions of British prime ministers (since Walpole in 1721) and American presidents (since Washington in 1789) with facial hair. (I’ve included Margaret Thatcher amongst the clean-shaven. One assumes she shaved her plums, anyway.)
It’s been a while since we’ve had any facial hair on either side of the Atlantic, which is quite a shame. The last British PM with a moustache was Harold Macmillan who left office in 1963; and you have to go back to 1913 and William H. Taft to find a US president with whiskers.
