McLaren are reportedly considering a shock engine partnership with Red Bull - just months after CEO Zak Brown accused his F1 rivals of "cheating" in a bitter cost-cap row.
Brown and Red Bull team principal Christian Horner became embroiled in a war-of-words last year after the world champions breached 2021 budget cap rules.
But McLaren chief Brown looks ready to put that rivalry to one side after it emerged Red Bull were being weighed up as an option for a potential power unit supply deal.
