One still in hospital after fire
Williams have confirmed just one team member now remains in a hospital following Sunday's garage fire in Barcelona.
Personnel from several teams fought a blaze that began 90 minutes after Pastor Maldonado had given Williams their first victory for nearly seven and a half years.
Three from Williams had to be transferred to local hospitals, with two having now returned home after receiving treatment for smoke inhalation.
The one still in hospital suffered burns in the incident, but is stable and will return to the United Kingdom within the next 48 hours to receive further medical care.
Williams add the team member concerned is "in good spirits", and that his family are "in constant communication".
Team principal and founder Sir Frank Williams said: "I was pleased to welcome back to the factory the majority of our team this morning.
"One of our people remains in Spain for further medical assistance, but we are all looking forward to his imminent return.
"Everyone at Williams F1 is extremely relieved that this event was contained as quickly as it was and the damage which occurred was, relatively speaking, limited in its nature.
"While the incident was unexpected and definitely most undesirable, it has demonstrated the genuine cohesiveness, camaraderie and spirit of co-operation that exists within the Formula One paddock.
"The astonishing response from the teams and other paddock personnel was immediate, unconditional and overwhelming."
