Speaking to the official Formula One website, Formula1.com, FIA President Max Mosley has warned that any team caught spying in future would face banning from the World Championship.

"You can never stop what someone has got in his head," admitted the Englishman, "but we can stop the transfer of information in written or electronic form. And if you are prepared to check - and we have demonstrated that we are - then somebody using such information would be very unwise because in a modern F1 team you cannot do it without leaving traces, and we will find those traces.

"Next time, whoever it was, I don't think they would stay in the championship," he continued. "In the case of McLaren everybody said 'oh, a hundred million dollars', but the alternative would have been to exclude them - and that would have been more expensive!"

Referring to the way the spy saga was handled, he said: "I would say that we did it the right way at each stage. When we had the first hearing on the 26th of July we were all very suspicious. We did not really believe that the only person involved was Mike Coughlan, but we had to find clear evidence and there was not sufficient evidence to convict them.

"Then when we had the second hearing there was enough evidence, and although we were greatly attacked in the English press I think that any objective person would say that there was quite enough. Then when we conducted the detailed inquiry and looked at all the emails and everything then the evidence became absolutely clear and overwhelming. But the people who didn't want to believe it still don't believe it."

Asked if he was "satisfied", following the FIA's investigation of the new McLaren, Mosley said: "In the end such attempts will never be 100 percent satisfying, but we are reasonably confident. I hope that the main points have been eliminated."

While when asked if the Woking team had been ordered to halt further developments in certain areas of their car, he replied: "There has not been an ordered halt in the development in certain areas, but regarding the three elements that clearly connect it (the car) with Ferrari, let's put it like this, they have agreed not to introduce them in the new McLaren."

In recent weeks, Mosley appears to have made progress to curb spending in F1 by imposing a budget cap, however, this hasn't gone down well with all the teams.

"I think for a long time the feeling was with the big manufacturers that cost doesn't really matter, that they don't care," he said. "Now everybody understands that they do care and in fact it became of big importance to them.

"The teams at the last meeting were strongly in favour - or almost all of them were strongly in favour - of a cost cap rather then specific regulations," he continued, "because with the cost cap the amount of money is limited, but you can spend it any way you want, whereas if we start saying this is for the use of the wind tunnel or the computer, one team has a big wind tunnel, the other has got a big computer, so you end up getting everybody unhappy.
