Button supports Russian Grand Prix
"This is not a day of work, it's a day of enjoyment," the Briton told reporters after taking a few leisurely laps in his race car round the Kremlin walls on his first trip to Moscow.
"I've always wanted to visit Moscow. I haven't seen much of the city as we only arrived two days ago," the McLaren driver added.
"It would be a good idea [to have a Grand Prix here] as I definitely want to come back."
Moscow officials hoping to bring Formula One to the capital are negotiating with commercial supremo Bernie Ecclestone.
"We're aiming to have the race here as early as 2012," general director of Bavaria Moscow City Racing (BMCR) Derk Sauer told Reuters.
"The [race] contract is not done yet but we're getting very close."
Ecclestone said last week that having a race in Russia was his priority.
