Oh what a tangled web is being weaved between Red Bull, Renault and Mercedes, but then such political machinations and complications are part of the very fabric that makes Formula 1 what is today.
The fallout between Red Bull and power-unit supplier Renault has been long and painful this season, and with what appears to be a complete breakdown of trust between the two parties, a divorce is now imminent.
Despite a contract being in place through to the end of 2016, the understanding is that Red Bull has officially notified Renault in writing of its intention to terminate the deal at the end of this year.
