The silly season continues, in a way.
Artem Markelov's father has been taken into custody as part of an investigation into corruption, which could affect his backing - Markelov has been talking to Williams about a drive for next season. It's also been rumoured that Kubica's found some more backing, while Williams have said that they'd be happy to take both Ocon and Russell for 2019...if Mercedes stump up $20m for the pair of them.
There's more, as Sirotkin is apparently now in talks for the vacant Toro Rosso drive. Pascal Wehrlein is an option, but he looks set for one of the Mahindra FE drives.
So who's left on the table for Tost, Marko and co? Drivers with superlicense points and who remain uncontracted for next year are Ocon and Russell (but Mercedes links have nixed their hopes), de Vries (although he seems set for a Formula E drive somewhere), Mick Schumacher (although that's unlikely), Anthoine Hubert (doing the maths, he's got the requisite 40 points - but it's way too early for him). Oh, and Brendon Hartley of course...
