World champion Sebastien Ogier opened up a comfortable lead over closest rival Ott Tanak in the second leg of the Wales Rally GB on Saturday.

Ogier, who secured his fourth straight world title in Spain earlier this month, will defend an advantage of 33.8 seconds over Estonia's Tanak in the final leg, with Belgium's Thierry Neuville a further minute behind in third place.

"I tried to go flat out for the whole day, pushing hard all the time," Ogier told the world rally championship's official website. "(On Sunday) I'll do what I can and see if it is enough."

Ogier, in his Volkswagen Polo R, kept Tanak at bay during eight speed tests which covered almost 100 kilometres on greasy roads in the Welsh fog.

Tanak cut Ogier's lead from 37.3 seconds to 24.8 after winning four of the first six special stages in his Ford Fiesta RS, but the Frenchman regained more time on his rival in the penultimate test at Aberhirnant.

Neuville, who escaped unscathed after his Hyundai i20 mounted a bank on Saturday morning, finished 12.6 seconds ahead of team-mate Hayden Paddon. Ulsterman Kris Meeke, in his Citroen DS 3, was in fifth place.
