Australian GP boss fears for event

Ecclestone was at the centre of a spat with Melbourne mayor Robert Doyle recently, amid questions about whether the high cost of the race brought good value to Melbourne.

In the wake of those remarks, Ecclestone said that if Melbourne officials wanted to cancel the contract before it expires in 2015 he would be ready to talk.

Walker, who is a close friend of Ecclestone, said on Friday that he believed F1's commercial boss had been insulted by the Mayor's remarks.

"I think he feels let down that a mayor of a capital city for the first time in 40 odd years would question the value of an F1 race," Walker told the Herald Sun newspaper. "A race that is equal in value to a World Cup or Olympic Games.

"He will make up his mind in 2014...there's no shortage of people who want a race."

With a host of countries queuing up for the chance to host a race, Walker said that being aggressive against Ecclestone would likely only result in the event being dropped.

"He was quite offended by those remarks and even though he has very good friends here, and is very proud of Melbourne attendances, he has many other options," he explained. "He doesn't want people to insult the brand."
