McLaren CEO Zak Brown has taken another swipe at Red Bull F1 team boss Chri🎉stian Horner for “making excuses” and “not taking ownership” over a number of issues.

Since McLaren’s resurgence on-tr🤪a♓ck, Brown hasn’t been afraid to lock horns with Horner.

Brown was vocal in his criticism of Red Bull when they excee💟ded F1’s cost ꩵcap.

He claimed Red Bull’s overspending ‘constituted cheati🐭ng’ which didn’t go down well.

More recently, Brown was outsp🍬oken amid Horner’s inappropriate behaviour scandal call𝔉ing for “transparency”.

Similarly, the American poked fun at Red Bull when they lost Adrian Newey, stating the team will likely lose more key personnel with “CVs flꦉoating around”.

In an interview with the , Brown shed light on his relationship with Horner and why i🍎t has deteriorated.

"I♔'ve known Christian for about 25, 30 years. We used to race against each other. I would say we used to get on,” h⛦e said.

"I believe in transparency. I believe in putting your hand up when you 𒁏get something wrong. The cost cap, the excuses behind that, I never really heard a 'we just got it wrong'. I heard excuses and not taking ownership.

"Whꦇen someone breaches the cost cap, and doesn't seem to kind of🥃 take it seriously, that's kind of hitting the integrity and core of the sport.

"To me, it's not personal. It's protectiꦗng our sport.”

Brown again made reference to Horner’s pre-season controversy, adding✱ it wasn’t “consistent with our values”.

"And when I see things not consis🐟tent with our values, I'm going to speak up about it because it's important people understand where we're coming from,” he added.

"I realise that's not necessarily always going to be popular, or make friends with everyone in the pit lane, but as long as I'm friends with McLaren, our fans, our partners, that's what's most importa꧑nt to me."
