Jari-Matti Latvala took control of Rally Finland with a dominant display on Saturday to put some breathing space between himself and team-mate Sebastien Ogier.
Finn Latvala began the day with a three-second advantage at the top of the race standings and added five more stage wins to extend his lead to 13.2 seconds.
Championship leader Ogier, who has won five races so far this year, topped the timesheets in Saturday's three other stages but is likely to have to settle for second place in Finland.
Norway's Mads Ostberg (Citreon) lies in third spot, one minute 28 seconds behind Latvala, after taking advantage of team-mate Kris Meeke's misfortune.
The Northern Irishman was placed third when he crashed out on stage 16, running wide and hitting a tree.
