ENSTONE-BASED Renault strengthened their grip on fourth place in the F1 constructors championship with a double points finish in the Monaco Grand Prix.

Nico Hulkenberg was eighth and Carlos Sainz tenth in the principality.

The results have seen Renault move five points clear of fifth-placed McLaren.

Kevin Magnussen and Romain Grosjean came home in 13th and 15th respectively for Banbury-prepared Haas.

There was more woe for Grove-based Williams, however.

Sergey Sirotkin finished 16th, hindered by an early drive-through penalty due to all four wheels not being fitted to the car in the allotted time before the start.

Lance Stroll picked up two punctures and was 17th.
