Exclusive: Document discovery threatens to delay Christian Horner F1 return PlanetF1.com has discovered documents which suggest Christian Horner's return could take even longer than planned.

Discovered a document detailing how and when Alpine shares can be sold, and it's not good news for Christian Horner. #F1

Christian Horner accused of 'lying' in extraordinary Helmut Marko attack Former Red Bull team principal Christian Horner has been accused of "lying" by Helmut Marko in an astonishing interview.

Some incredible comments from Helmut Marko. He's branded Christian Horner a liar, while offering no proof/examples, and pedalled a conspiracy that is debunked with 20 seconds of research. Not sure what he was really trying to achieve with this one... #F1

Have seen claims Piastri's family couldn't get passes to AD and McLaren wouldn't help. Heard this over the weekend and chased it up. Utter nonsense. Was a late decision to attend so strings were pulled for last minute passes. Common practice for last minute decisions. #F1

Jack Doohan F1 lifeline emerges as part of new 2026 programme A deepened relationship between Toyota and Haas could pave the way for Jack Doohan to return to the F1 grid in F1 2027.

There's cause for Jack Doohan fans to be optimistic. There's some exciting stuff in the pipeline for him, should everything go to plan (and no obvious reason it shouldn't from those I've spoken to). #F1

Nice moment post race between GP Lambiase and Will Joseph. #F1

A long-serving mechanic from Ferrari was sent off in style. Once security let them through...! #F1

This is our first physical look at a 2026 #F1 car. It's a 3D print produced by the FIA. Looks a cross between Super Formula and CART. #AbuDhabiGP

Ran into a familiar face. @thomasrandle49 is an F1 Expert host this weekend. Don't come much more expert. Also, Seth McFarlane impersonator! #F1 #Supercars

McLaren boss Zak Brown underscores driver equality in title charge As McLaren dominates the Constructors' Championship, team boss Zak Brown has made an incredible revelation over the Drivers' title.

As we head into Abu Dhabi, a conversation I had with Zak Brown back in May has proved prophetic. #F1

Lawson* !

Liam Lawsom currently meeting with Helmut Marko. Isack Hadjar was very happy yesterday, he seems safe, and a Red Bull driver for next year. Liam...? #F1

Smooth surface plus high speeds equals huge tyre forces and wear through sliding, especially front end. Pirelli is wary of cuts seen on Friday. No known concerns yet post Sprint, but investigations are ongoing. #F1

Was that the fullest Sprint ever? Yuki did well at the start to helpax, after that it was all quite processional. Good drive from Oscar, but there was precious little action. #F1

Adrian Newey was an interested observer on the Sprint grid. #F1

McLaren has spoken about Piastri helping Norris for the title in view of the threat Max poses. The decision, a quick 'no' from Piastri. He's still in the fight, after all, so can't really blame him. #F1

Newey: "I’m looking forward to taking on this additional role as we put ourselves in the best possible position to compete in 2026, where we will face an entirely new position with Aston Martin now a works team combined with the considerable challenge faced by the new regs." F1

Setup day done. #F1

After 30-something hours in transit, I've arrived in Qatar. #F1

Speculation surrounding the Madring not being ready for 2026 is "nonsense" I'm told. Lots still to do, of course, but plenty of time. #F1

Are you okay?

McLaren summoned to the stewards for plank wear on both Lando Norris and Oscar Piastri cars. Huge in context of the championship. #F1

Max Verstappen now has a better win rate in F1 than Michael Schumacher. 29.87 per cent for Verstappen versus 29.64 for Schumacher. #F1

The Turn 1 clash with Lawson has left Piastri with some minor damage. Nothing race threatening, but isn't helping his cause. #F1

How and why were marshals on track at Turn 1 as the field came through? So soon after Mexico, that demands an explanation from the FIA. #F1

Williams has radio issues with Alex Albon. #F1

New PU elements for Yuki Tsunoda, plus set-up changes and a different spec rear wing mean he'll start the Las Vegas GP from the pit lane. Not a huge penalty given he was P19... #F1

Alpine fined 5000 euro for failing to electronically return Franco Colapinto's tyres correctly. #F1

Sainz will maintain third. His unsafe rejoin was, in fact, safe according to Lance Stroll and so there is no penalty. #F1

Mercedes in the clear on set-up sheets. An IT security issue meant forms were submitted in time, just not received by the FIA. #F1
