'This is how late stewards appear to be ruling on Mercedes protests'

According to F1-journalist Erik van Haren, employed by De Telegraaf, the verdict of the stewards is expected around 18:30hrs UK time. Currently, there are two cases pending, one against Max Verstappen for overtaking Lewis Hamilton under the safety car and one against the FIA for not letting all cars unlap under the safety car.

It is unclear if the FIA will announce the outcome of both cases at the same time. The team that loses tonight will appeal again, Martin Brundle expects. Going to the CAS (Court of Arbitration for Sport) is not excluded either. 

Update on expected date of judgement

Uitspraak wordt rond half elf, dus half acht in Nederland, verwacht. #F1

Christian Horner just said to me nothing decided yet but he expects a decision tonight. Presumably the losing side will then appeal anyway.
