Afternoon everyone, it's getting dark in Singapore, and we're ready for the final practice session before qualifying.

The track looks spectacular as Christian Klein storms down the straight in his Hispania - can he adjust to this last-minute call-up?

Lots of discussion about turn ten - Lewis Hamilton described the chicane in less than glowing terms yesterday - we'll see if anyone struggles with it in this hour.

We're away - and there are plenty of drivers heading straight out to test their set-ups - looks like a few drivers are opting for intermediate tyres.

The track is wet, and already we've heard Jaime Alguersuari being told how slippery it will be - it should be an interesting session especially if qualifying throws up different conditions.
