Organisers for this weekend's Singapore Grand Prix say there are no plans to amend the racing programme over ongoing concerns with air quality and circuit safety, though it insists it is monitoring the evolving situation.

A thick smog has shrouded the city-state ahead of Singapore's hosting of its annual night race, prompting a number of sporting events to be cancelled last weekend.

The haze stems from farmers in neighbouring Indonesia burning crops to clear land for agriculture and while it isn't an unusual event, this year has seen the smog rated by experts as 'unhealthy'.
