May 30 (GMM) The F1 circus will leave Turkey without a decision about the sport's tyre supplier for 2011.

The sport arrived in Istanbul earlier this week amid speculation Pirelli had been selected and would be unveiled as Bridgestone's replacement before the event was out.

But it then emerged that Michelin's Nick Shorrock had arrived in the city, and the French marque's competition boss met for 90 minutes with team bosses on Sunday.

The meeting broke with team figures saying only that a decision has not been made and is not due for a few more days.
