Lotus has announced that Kimi Raikkonen has been withdrawn from the Young Driver Test at Silverstone after 'clarification emerged regarding the scope of tests that could be conducted by race drivers for Pirelli this week'.
The Finn was due to get behind the wheel of the E21 on Friday to work on the new Pirelli tyres but will now not appear after the team decided it was more beneficial to continue running one of its test drivers to work on car development work.
As such, Nicolas Prost – who is on track today for the first day of the three-day session - will return to action on Friday for a second day of running after Davide Valsecchi's day on track tomorrow.
"Once details of what race drivers were allowed to do here became apparent, we would have only been able to conduct a very limited programme with Kimi,” trackside operations director Alan Permane said. “If we were to run him, it would compromise the other development work we want to do with the car here.
“By running Nico again we'll be able to build on the work already carried out and hopefully be in the best position to develop the E21 ahead of Budapest, whilst also conducting the necessary tyre testing for Pirelli."
News that Raikkonen won't now appear comes on the back of Red Bull's announcement that Mark Webber had also stood down
from his planned run on Wednesday.
