F1 teams were paid more than $500 million in prize money in the last three months - the most expensive quarter for F1 in history. #F1.

It's been a rough ride for @AlpineF1Team in recent seasons. #F1.

Sergio Perez to Cadillac. While it's being reported that an announcemt is imminent, multiple sources told me today that is not the case. #F1.

Cadillac driver announcement reports are premature, according to several sources I spoke with today. #F1.

A potential £50 million pay out for Christian Horner. Company records suggest he was on approximately £9million/year. With his contract set to run until 2030, that could result in a very healthy settlement. #F1.

Documents filed in Austria show there was an ownership change at the very top of Red Bull in the weeks prior to Christian Horner's axing. Could that have been a contributing factor in his demise?.

There are believed to be other departures from Red Bull. Multiple sources says Chief marketing officer Oliver Hughes and Group Director of Communications Paul Smith have also left. #F1.

Fred Vasseur is now the second-longest serving team principal after Toto Wolff. Wolff took charge of Mercedes in January 2013. Vasseur took over at Ferrari in December 2022, around the same time Andrea Stella did for McLaren. #F1.

Christian Horner has been sacked by Red Bull. Laurent Mekies to take his place. Huge news. #F1.

Fabulous start to the Austrian GP. Kudos to McLaren for letting its drivers race. It's a bold, brave, and every F1 fan can (and should) be thankful. Zak Brown told me: "Our drivers aren’t asking for favouritism, they’re asking for fairness. May the best man win." #F1.

A bridge hit by a recovery truck after the F2 race in Austria brought down an advertising bridge. No other damage, the FIA has confirmed to me. #F1.

Brad Pitt in McLaren garb from his outing at Circuit of The Americas. #F1

Carlos Sainz has confirmed he will not contest the FIA presidential election. "Present circumstances are not ideal to set the grounds for my candidacy," he wrote. #F1.

Qatar GP update- Missile strike on a US base in Doha as Iran/Israel conflict continues. Calls for a ceasefire from the US. No immediate threat to the running of the GP and the situation is being monitored. Race is five months away. #F1.

Liberty Media's $4.8bn acquisition of MotoGP has received unconditional approval by the European Commission. Liberty will own F1 and MotoGP. There were antitrust concerns that have clearly been satisfied. Massive news for global motorsport. #F1 #MotoGP.

This is what the Thailand F1 track will look like, based on details available so far. Please excuse the poor Photoshop job! The circuit is about 5.7km in length, pit complex at the top of this map, going anti-clockwise. #F1 #Thailand

It was put to me that with the Canadian GP extension was the event swapping to a rotational event, hosting races in '29, '31, '33, and '35. Have confirmed with FOM that is *not* the case and it will run every year until 2035. #F1.

Canada to remain on the F1 calendar until 2035. Good news, great event that has a habit of producing exciting racing. #F1.

This is an excellent explanation as to how and why the Canadian GP result took so long. It's not a knee jerk opinion (as some have written), it's a considered and informed run down of the process as it is, and it's weaknesses. Excellent journalism. #F1.

And many, many hours later, the winner of the Canadian GP is. unchanged. Red Bull's protest was rejected, so Russell remains the race winner after a very, very long wait. #F1.
