Dennis 'drained' after emotional weekend

And the McLaren CEO revealed his team may decide not to appeal their penalty after all.

The Hungarian race stewards denied McLaren all constructors' points scored today by Hamilton and Alonso - a total of 15 - as punishment for yesterday's controversial pitlane incident, which saw Alonso hold up teammate Hamilton.

Asked how he felt after today's race, a downcast Dennis told ITV: "A bit of emptiness at the end of an extremely difficult weekend. I so drained, it's difficult to have any emotion left.

"What happened yesterday was really unacceptable. We have a very, very strong commitment to parity. But this was one of those times where as hard as you try, there's always a deviation from our plans, that put the team in extremely difficult position.

"This cost us today constructors' points, if we don't follow through with lodging an appeal."

McLaren gave notice that they intend to appeal the decision within an hour of the stewards' ruling, as required by the regulations.

However, they need to submit a formal appeal or notify the FIA they will not appeal, and Dennis said this will be done once the team are back in the factory.

"That matter will be discussed and we will inform the FIA," Dennis said.

He also emphasised both drivers were to blame one way or another for the mess.

"I don't think either driver is blameless in this situation," Dennis said. "We should have been a little bit more aggressive in handling this situation, but it's not really my style.

"There is a tremendous amount of pressure in the team, and it comes from two guys who are phenomenally talented and who are leading the championship and are looking at every advantage possible.

"There's frustration and sometimes mistrust with both of them. It's tough on us, but we will not deviate away from equality. It's the foundation of the company.

"In the end we are still leading both championships. We have taken a difficult emotional blow, but we just have to dig deep and move forward."
