LAP 7/53 - VERSTAPPEN IS PAST
Verstappen slips past Bottas with little difficulty, and the Finn appears to make little effort to block him off. If his role was specifically to block his team's rival, he blew it.
Verstappen is in fifteenth, behind Bottas who just set the fastest lap. There's no change in the top 10 at the moment, but Hamilton will need to get a shift on rather than stay in sight of his rival's Red Bull.
Hamilton takes Alonso around the outside. There's a yellow flag in sector one with potential debris on turn two.

13:00 - FORMATION LAP BEGINS
The rain is coming down near the course, and is expected to arrive in due course, but when it does it should be a light shower in five minutes. Let's see.
12:50 - RAIN CLOSING IN?
The race has been blighted by poor weather this weekend, and it looks like there could be more to come.
12:35 - BOTTAS GRID PENALTY
As you can see below, Valtteri Bottas is way back on the grid after taking a new power unit. Given Red Bull are similarly troubled with position, perhaps Mercedes are content to allow Bottas to perform a blocking role early in the pack rather than closer to the top places. It makes sense, in a cynical way.
12:20 - HAMILTON ON VERSTAPPEN
Earlier in the week, Lewis Hamilton attempted to put the pressure on his championship rival, Max Verstappen.
Hamilton said: "Ultimately we all have to be smart, and know that there is a time you are not going to make the corner.
It's all about that you get to live to fight another day for the next corner. Naturally through experience you find that it's not all won in one corner. I'm hopeful we won't have any more incidents through the year.
Nevertheless, Hamilton expects Verstappen to remain aggressive.
"He's never done it in the past so I don't expect it to happen," Hamilton explained.
"And I think that's the way I will approach things, not expecting it, and just try to create the space that's needed.
"I'm sure he will and we will continue to learn."
