Lewis Hamilton to serve 15-place grid penalty in Belgium

Lewis Hamilton will serve at least a 15-place grid penalty in Sunday's Belgian Grand Prix after taking on a fresh engine.

The reigning world champion, who leads his Mercedes team-mate Nico Rosberg by 19 points in this year's title race, will start no higher than 16th after his team confirmed he has taken on a new turbo and MGU-H, exceeding the five he is allowed before a penalty is enforced.
