LONDON (Reuters) - The future of the Italian Grand Prix at Monza remains uncertain after this year with Formula One's commercial supremo Bernie Ecclestone saying on Friday that a deal had become more complicated.

The historic circuit near Milan, which has been on the calendar every year bar one since the championship started in 1950, will host Italy's only race in September but has no contract beyond 2016.
