Maria de Villota remains in a critical but stable condition at Addenbrooke's Hospital two days after her accident while conducting a straight-line aero test with the Marussia F1 team at Duxford.

The Spaniard lost her right eye and suffered further head and facial injuries in the accident, which saw her car collide with the tail-lift of the transporter that had been used to take her Marussia MR-01 to the testing venue.

In a statement issued by the Marussia team on Thursday evening, the de Villota family said it was overwhelmed by the support shown for the 32-year-old since the accident took place and was encouraged by the fact that she remains stable having undergone emergency surgery overnight on Tuesday.

"Maria remains in a critical but stable condition here at Addenbrooke's Hospital," he sister Isabel said on behalf of the family. "While there is no further news than that at present, we have at least been able to take encouragement from the fact that Maria has remained stable throughout since the accident, particularly during the first night following such a lengthy surgical procedure as she experienced yesterday.

"We, the family, are supporting each other here at Maria's side and we take great comfort from the remarkable medical care she has been receiving. We remain positive and this is due, in no small part, to the overwhelming expression of love and support for Maria from every corner of the world. We would also wish to thank everyone at the Marussia F1 Team for all the care and attention they have shown us over the past few days."

De Villota's accident was a topic raised during Thursday's FIA press conference at Silverstone ahead of the British Grand Prix, with countryman Fernando Alonso admitting he had been shocked to hear news of what had happened.

"Obviously we are very worried for this situation because we are still waiting for some more news," he said, speaking before the de Villota family statement was released. "We only know what you all know and there are still some difficult days until the situation is completely clear. The operation has passed completely etc.

"Sad days, for sure, completely shocking when you hear the news and how what happened is possible. Obviously we don't know all the information it's difficult to talk about the reasons etc until we know the official version but at the moment, it's so difficult to imagine how this can happen."
