Lewis Hamilton survived constant pressure from Sebastian Vettel in Belgium to halve the gap at the head of the drivers' championship. Red Bull's Daniel Ricciardo finished third, but it was a bad day for Max Verstappen.
Mercedes' Lewis Hamilton won the 2017 Belgian Grand Prix and closed the gap on championship leader Sebastian Vettel.
The Englishman crossed the line in Spa 2.3 seconds ahead of the German - his 58th GP win in his 200th F1 race - who remains seven points clear. Hamilton's fifth success in 12 races came a day after he equaled Michael Schumacher's all-time record of 68 pole positions.
Australia's Daniel Ricciardo gave Red Bull a third-place finish after taking advantage of a safety car stoppage.
On an entertaining afternoon, there was drama in the Force India camp as teammates Sergio Perez and Esteban Ocon collided. The resulting deployment of the safety allowed Vettel to almost wipe out Hamilton's lead, much to the frustration of the Briton.
There was disappointment for thousands of Dutch fans who had traveled to Belgium when Max Verstappen retired on the eighth lap after a loss of power - his sixth retirement of the season.
