The lemming’s reputed to leap
From clifftops, to die in the deep.
But none of that’s true,
It’s what Britishers do
When they follow some self-serving creep
And vote ‘Leave’ while their minds are asleep.

Leap Day entitles the poet to employ a Leap Line, the better to evoke the Leap of Faith, lately made by our British allies, into the icy depths of worldwide contempt and opprobrium.
