Here is the poem upon the BBC Newsnight website. It says

Sissay said: “Whether people like it or not a writer’s relationship with his or her words is more powerful than any commission, publication, TV show or award. My eight lines is entitled Rest, to try and capture the decisive moment before the writer sleeps on the night of the award.”

—————-

Rest

I expect you might at some point tonight

Beneath the sheets before sleep

Still reeling from the flaying lights,

Want or more likely seek

Rest. There is no manifesto in this

Nor snake-like list of things to do.

There is no tomorrow either,

There’s poetry as ever and you.
