16:30 There's the chequered flag.

16:30 "I must have had a massive gust [of wind] going into Turn 4," says Vettel as he describes that incident.

16:29 Lots of drivers making late errors - Vettel runs wide at Turn 4 and has to go right around the gravel trap on the grass to rejoin.

16:29 Top 10: 1 Hamilton; 2 Bottas; 3 Raikkonen; 4 Vettel; 5 Verstappen; 6 Ricciardo; 7 Hulkenberg; 8 Palmer; Massa; 10 Sainz

16:28 As they head onto their final lap or two, here's the near-certain end-of-day order:

16:28 A little trip through the gravel for Bottas late on his long run, while Grosjean skitters over the chicane run-off.

16:27 We'll bring you our usual comprehensive analysis of the long runs and relative car pace later today, as well as all the post-session reaction from the teams and drivers.

16:27 Less than four minutes to go. Friday can be a pretty cagey day in the paddock, but it'll be fascinating to see if the Mercedes drivers are perky and the Ferrari drivers a bit disappointed when talking about their upgraded cars this afternoon - that's what the timesheets suggest the mood will be.

16:24 Raikkonen asks "is the lap time really bad?" and is told "it's quite comparable to the others" as the long runs continue with Mercedes slightly faster.

16:22

16:22 McLaren tells Vandoorne he'll get a steering wheel change when he pits.

16:18 "Checo, how is the balance?" asks Force India. "The front is not working at all. The balance is very bad," replies Perez.
