Romain Grosjean is given a 10-second time penalty for causing the collision that ended Esteban Ocon's race.

Grosjean is currently last.

"Important to close the gap," Valtteri Bottas is told. The Finn responds by putting in the fastest lap of the race so far and the gap - having dropped down to two seconds - is back to 1.6 seconds.

Fernando Alonso resits the urge to get involved in a tussle with Lewis Hamilton. That's not his fight. Hamilton moves past the McLaren with little trouble down to Turn One.

Into sixth.

Felipe Massa, Fernando Alonso and Lewis Hamilton.

An old school ding dong about to ensue.

Up next for Lewis Hamilton is Fernando Alonso. The McLaren is 1.2 seconds ahead of the Mercedes but Hamilton's last lap was four tenths quicker than Alonso's. Should be on him soon.

Vettel is comfortable, Bottas isn't in the DRS zone. He will want to get these soft tyres as far into the race as possible.

"I see Vettel is pulling away," says Lewis Hamilton.

"The gap to Vettel is 15 seconds but I think he needs to start managing more," is the reply from his race engineer.

Helen Nelson: Thanks #bbcf1, external for the coverage. Making a three-hour delay at Thessaloniki airport in Greece more bearable.

Ruairidh: With the math degree I have and the progress @LewisHamilton, external is making, i predict Lewis will be in P1 by lap 25.

Kristine Kirby:@LewisHamilton, external in 8th. Seriously, I can't tweet fast enough for how spiffily Lewis is moving up through the pack.

Just Mick: Hamilton more likely to make podium if there ISN'T a second safety car. He doesn't want leaders potentially getting a free pit stop.

I can't keep up with Lewis Hamilton's charge! Both Renaults are passes with little trouble and he is now eighth.

Meanwhile, Daniel Ricciardo is also making moves up the field. He had dropped right to the back after an early spin but he's now up to 12th.

This confirms the pace we saw from Lewis Hamilton on the soft tyre in practice on Friday. If we get another safety car, he can win this grand prix. His pace on these soft tyres is quite stunning.

Nico Hulkenberg's super-soft tyres are apparently on the highway to the danger zone.

That's good news for Lewis Hamilton, who has the ninth-placed German in his sights...
