There's a special family connection between the Prime Minister and bubbemeises - old wives' tales.

David Cameron's 16th-century Jewish ancestor Elijah Levita was the author of the Bovo Bukh, a Yiddish version of the romances that were popular in Europe at the time. Bovo refers to the knightly hero of the story, the good Sir Bevis.

The Bovo Bukh later became known as the Bove-Mayse, the Tale of Sir Bevis - and hence bubbemeise (which is thus not derived, as often believed, from bubba).
