F1 LIVE: Two drivers under investigation at Belgian GP as Red Bull without key man

McLaren duo Oscar Piastri and Lando Norris are battling for this year's F1 world title, with the Australian leading his team-mate by eight points ahead of the Belgian Grand Prix. The pair have won all but three Grands Prix this season to put themselves well ahead of their rivals.

Piastri appeared to be coasting to his first championship victory a couple of months ago after winning the Spanish Grand Prix. But Norris clinched victory in Austria and at Silverstone to put himself back in the mix. Meanwhile, Red Bull star Max Verstappen, who has won the last four Drivers' Championship titles, is 69 points off the lead but does have two race wins under his belt. The action in Belgium begins with the first practice session at 11.30am BST, with Sprint qualifying scheduled at 3.30pm. Follow the Express Sport live blog below for the latest F1 news.
