Christian Horner secured a pay-off from Red Bull worth 60m euros (£52m)

Christian Horner formally leaves Red Bull a very rich man with unsated ambitions in Formula 1.

The severance of the 51-year-old's links with the team he made one of the most successful in the sport was confirmed on Monday.

Red Bull gave no details about the settlement terms, but BBC Sport has been told by a source close to the team that Horner secured a pay-off worth 60m euros (£52m).

The move frees Horner up to return to F1 in the future - if he can find a project that is willing to take him on board.
