Keen that in the wake of the Turkish Grand Prix there is no further speculation regarding possible bias, Red Bull boss Christian Horner insists that his team's drivers are free to race one another.

In a move widely seen as Sebastian Vettel's fault, the German crashed out of the Turkish race while attempting to pass his teammate. In the aftermath however, Horner and team advisor Helmut Marko appeared to suggest that the blame actually lay with Mark Webber.

In a clear display of damage limitation, further comments were issued in an attempt to clarify what happened and what was said, while both drivers attended a 'kiss and make up' meeting at the team's HQ. Vettel, subsequently dismissed talk of bias towards him while Webber has signed a one-year extension to his contract.

Speaking to BBC Sport, Horner, keen to end the speculation and show that it's business as usual, said that both men were free to race one another, though there were to be no repeats of the Istanbul incident.

"They will be racing each other, the most important thing is they respect they are driving for a team and I believe they do," he said. Adding that be believed Webber and Vettel had both "learnt from what happened at Istanbul" and that, "if they find themselves in that situation again, they don't push themselves so hard."

Referring to the comments he and Marko made after the race, Horner said: "There were a few opinions that were voiced without all the facts available. Emotions are running high, one or two comments were made without all the facts to hand.

"In the cold light of day it was a racing accident," he added, "nothing more, nothing less. It was wrong to blame either driver. Both drivers are professionals, they're both grown-ups, they've both been in that position racing wheel to wheel, both with themselves and with competitors, and I'm sure it won't happen again.

"It's wrong for us as a team to apportion blame," he admitted. "They both got themselves into a situation which was arguably over the limit. The result was that both of them found themselves in a situation that they didn't want to be in, the result was contact and a loss of points for the team and a gift of points to our rivals."

When asked about Vettel's continued claims that he was not to blame for the clash, Horner said: "I don't think either driver is going to stick their hand up and say 'yes, it was all down to me'. As Mark has said, both drivers will go to their graves with differences of opinions.

"We got the drivers together, sat down with Adrian (Newey), with Helmut and we had a very positive and constructive meeting. Mark is one of the hardest guys in grand prix racing, he's is a tough racer, a tough competitor. He's mentally very strong and he's in the form of his career at the moment and he won't give a quarter, and arguably the person you least want to be overtaken by is your team-mate.

"I think both drivers recognise from a team point of view that it was a disastrous outcome," he added. "They were sorry for the team, the body language between them was very relaxed because they are good team-mates, they work well together and they have raced each other successfully wheel to wheel on several occasions and an incident like this we won't allow to disrupt that relationship."

In response to claims that he had told Webber's engineer to tell the Australian to allow Vettel to pass, Horner replied: "I don't think I actually said 'move'.

"I don't talk directly to the drivers until after the race," he continued. "Mark's engineer had no instruction to tell Mark to move out of the way... 100% clear."

"We were allowing both drivers to race and I don't think that is wrong. What I do believe is wrong that they unfortunately drove each into each other! Red Bull is about racing, it's not about processions, otherwise we would have given team orders after the first turn or the pit stop. "We had two guys that we are trying to give equal opportunity to win the world championship and win races being heavily pressured by the McLarens."
