Max Verstappen has improved to move within half a second of Valtteri Bottas. Plenty of the cars are sporting red boots, but not the Mercedes just yet. Still on softs.
Silverstone's history of British Grand Prix uncertaintypublished at 10:11 British Summer Time 14 July 2017
The future of the British Grand Prix has been left uncertain after Silverstone's owner confirmed it had activated a break clause to cease hosting the race after 2019.
It became the event's permanent home in 1987 but that status has been in doubt several times over the years.
BBC Radio Northampton take a look...

Dramatic clouds above Silverstone, but they look worse than they are. Weather forecasts suggest almost no chance of rain for either practice session today.

Max Verstappen, out now on super-softs, improves with 1:29.786 to go P3. That was on a lap when he had a twitchy moment as well. Red Bull appear to have the pace here.

Woah! Or should that Bwoah?
Big moment for Kimi Raikkonen on the exit of Brooklands as the rear of his Ferrari slides left and right.
He holds it together, but there's got to be some concerned faces in the Ferrari garage? Both Raikkonen and Sebastian Vettel have had moments in this session.

Hot boxpublished at 10:00 British Summer Time 14 July 2017
Problems for Pascal Wehrlein. Sounds like he's got a hot gearbox and he's told to box so Sauber can have a look at it.

Bit of a scrappy session for Vettel so far. Big spin in last right-hander at Maggotts; now over kerbs at Turn Four

Mercedes are back out and looking very mean.
Valtteri Bottas flies through the three sectors, nailing a lap in 1:29.106. That's quicker than last year's pole lap by Lewis Hamilton, who did 1:29.287.

Neil Boulton: Surely Swindon's Magic Roundabout needs to be included in any British Grand Prix?
I had this cracked when I lived in Swindon. Not as scary as it looks.

Plenty of tinkering going on in garages up and down the paddock, including on Fernando Alonso's McLaren.
Marcus Ericsson decides its time to break the silence once again. Jolyon Palmer also heads out. He's the only driver who hasn't set a time yet.

It's been a pretty low key session so far with not a great deal of running.
A number of fans entertain themselves by chatting to the chap that dresses up as the orange Max Verstappen lion.
Just under 45 minutes to go.

Your ideal British Grand Prix circuit?
Lloyd Hibbins: 2 laps of the M25 would satisfy race distance, but would be a bit dull. Watching the cars go over QE2 bridge would be great sight!
Joeee: Ideal circuit for Britain, why not have it in the heart of it in Stoke-on-Trent? It's basically the new Manchester
Dean Jeffery: I'd like to see the British GP eventually be at Circuit Of Wales.
Trip down memory lane for Mansell.published at 09:41 British Summer Time 14 July 2017
This weekend marks a double anniversary for Nigel Mansell.
The Briton triumphed at Silverstone for the first time in 1987 - 30 years ago - famously beating Nelson Piquet in a thrilling charge, breaking the lap record 11 times in the final 15 laps to win it on the final lap...

... and it's 25 years since he won his fourth British Grand Prix - and third at Silverstone - on his way to becoming the Formula 1 world champion for the first time.

Yellow flagpublished at 09:40 British Summer Time 14 July 2017
Yellow flags once again. It appears not all of the debris from Felipe Massa's Williams had been recovered. Most drivers were already back in the pits anyways.

Antonio Giovinazzi is behind the wheel of a Formula 1 car again for a first practice session.
He's subbing for Kevin Magnussen in the Haas and has quietly been going about his business. He's got the 18th quickest time - a 1:36.488.

Lewis Hamilton is chasing his fourth straight British Grand Prix win, and fifth in total.
The late Jim Clark, who also won five, is the only driver to have won four British GPs in a row.
