Wolff denies wanting to block Horner return to F1

Mercedes chief Toto Wolff has denied attempting to block Christian Horner from returning to Formula 1 but says his former rival could be facing "repercussions" for breaking "quite a lot of glass" during his time as Red Bull boss.

Horner was sacked from his positions as team principal and chief executive at Red Bull in July last year but has expressed an interest in returning to address what he has described as "unfinished business" in the sport.
