(Reuters) - Veteran media executive Edgar Bronfman Jr. has submitted a roughly $4.3 billion bid to take over Paramount Global ( PARAA ) through the acquisition of National Amusements, the family holding company that owns a controlling stake in the media company, a person familiar with the matter told Reuters.

The competing offer for the home of Paramount Pictures, the CBS broadcast network and MTV is a fresh twist in a sale process marked by a number of unexpected turns.

It threatens to undo a planned acquisition by David Ellison's Skydance Media, which signed a deal in early July. The agreement included a 45-day "go-shop period" that is set to expire on Aug. 21.
