Williams looks set to miss Tuesday's Formula 1 test running in Barcelona amid continued delays with its FW42 car.

After cancelling a planned shakedown of the car at the Circuit de Barcelona-Catalunya last weekend, Williams confirmed it would not take part in Monday's first collective running, but anticipated its car would debut on Tuesday.

However, the team has now issued an update say it is "more likely than not" to miss Tuesday, delaying the FW42's debut further.

"It is looking more likely than not that we will now not be in a position to run on-track until Wednesday at the earliest," deputy team principal Claire Williams said.

"This is obviously extremely disappointing, but it is unfortunately the situation we are in. We will be getting the FW42 on-track as soon as we are able to."

Williams had planned to run Formula 2 champion George Russell alongside reserve driver Nicholas Latifi on Tuesday, with Robert Kubica's planned maiden run on the car coming on Wednesday.
