Lance Stroll's Aston Martin has been delivered safely back to the team's mechanics. Some of the fans in the grandstand on the straight got a decent view of the Canadian's damaged car slowing coming to a stop.

How McLaren handled the situation last week was wrong.

Most people at McLaren have never won a championship and it changes the way you think. They are finding their way back to being a dominant force. It is not a switch you throw.

I am ok with them learning, and in the coming weeks, months and years we are going to see them becoming a dominance force.

Ah, most of you are going for no poncho if it's lashing down at a sporting event. Bit like prime minister Keir Starmer last night.

The safety car has been out to see how bad the standing water is around the 7.004km circuit.

The puddles are growing bigger and bigger around Spa as the rain is falling harder. The red flag has been shown once again by race control.

On the face of it it’s a huge weekend for Sergio Perez. The team have already said they will make decisions after the summer break.

I think the decision has been made that he has to be replaced, You know what you are going to get from Perez – quite frankly suboptimal results – the team need two drivers in that fight.

Max Verstappen is fighting to race wins single-handedly. I think they need to make the change.

Rain rate will increase now temporarily before easing around 13:00 local.

Max Verstappen currently holds the quickest time (if we can call it that) so far on the intermediates with a 2:01.565.

This is where we need the help from our cricket colleagues on how to do top-tier rain chat.

Lance Stroll has given everyone a brutal reminder of what these conditions can do.

But the weather conditions look quite dry for tomorrow so the way you roll out for qualifying will be how you want to roll out for the race tomorrow.

You will have to compromise qualifying today for the car you want to race tomorrow.

Poncho or no poncho if you are at an event and it starts raining?

There are lots of drivers sitting in the cockpit, but still no cars head out on to the very wet Spa-Francorchamps circuit.

Much like the spectators that lined the Seine in Paris last night, fans with no shelter at Spa already look completely drenched.

The track is open again and waiting for some shiny F1 cars, but no-one wants to come out and play just yet.

If the damage (to Stroll’s car) the front left corner, the elements of the front suspension are easily interchangeable.

The problem will be if any of those elements have snapped and punctured the main cockpit.

That is the safety cell in which the driver sits and the real core of the car. You cannot have any damage on that. I would keep my fingers crossed and hope.

The red flag has been cleared and the session will resume shortly.

Pirelli have chosen tyres in the middle of the range for this weekend's grand prix - the same pick as the previous two races at Spa.

Take your pick from the C2 (white, hard), C3 (yellow, medium) and the C4 (red, soft) - plus the green intermediate and full wets, which have been in use already today - for the 19-corner Belgian test.

The medical car was on the scene straight away following Lance Stroll's hefty hit with the wall. The Canadian looks to be OK, but will obviously be checked over by the team. The low loader has also arrived to take that beaten up Aston Martin away.

Lance Stroll has just crashed his Aston Martin up the hill after Raidillon and come to a halt with left-front suspension smashed. He's OK.

The front left wheel of Lance Stroll's Aston Martin is bent out of shape. It was a mighty slide for the Canadian at one of the fastest points on the Belgian circuit.

You can almost put yesterday to one side and start again from scratch now.

They have to figure out how to get their car working today, with an eye on tomorrow's race where it might not be quite as wet.

Lance Stroll has picked up damage at Raidillion. The Aston Martin has hit the barriers after sliding at speed across the track.

Lando Norris topped second practice yesterday but today, he's trying to grapple with rainy Spa-Francorchamps. The McLaren reaches Turn Seven and runs wide over the gravel.

The times on the intermediate tyres are all clocking over two minutes. Brief yellow flags are popping up on screen a drivers to try to avoid aquaplaning on the wet surface.

Daniel Ricciardo is still not happy with his car, so RB say "box, box" for the Australian to come in.
