Honda is willing to supply Red Bull with engines next season but McLaren boss Ron Dennis is blocking any deal, Formula One supremo Bernie Ecclestone said on Saturday.
"At the moment it would appear that Honda are happy to give them an engine and Mr. Dennis thinks they shouldn't," the 84-year-old told reporters at the U.S. Grand Prix.
Ecclestone said Honda agreed years ago with the governing International Automobile Federation (FIA) and himself that it would be willing to supply two teams in its second year back in Formula One and three in the third.
The Japanese manufacturer sold its works team and pulled out at the end of 2008, but returned this year as engine supplier to McLaren.
"They somehow . . . made a commitment to Ron that he had a veto and he doesn't want Red Bull," said Ecclestone. "Ron has said definitely not, as far as he's concerned. I don't know whether his veto will stand up legally."
