Hollingsworth, who is running the network's Latin American region from Miami, will transfer to London in November and report directly to the FCB international president Harry Reid with a brief to develop the network in Europe.
Hollingsworth will be charged with expanding the network, both through organic development of existing offices and clients, and through acquisition.
"We consider the UK, Germany, Italy and Eastern Europe all to be areas in which we want to expand, and we have big plans to action," Reid said.
He refused to be drawn further on FCB's acquisition strategy, but it is thought he will be looking to plug gaps not only in FCB's above-the-line offering, but also in the below-the-line sectors as the network seeks to enhance its positioning as a total communications outfit.
Douglas was ousted in December 1999, just over a year after taking up the role, in a tidy-up operation before the global merger of the FCB and Bozell networks. At the time of his hiring in July 1998, Douglas, who was previously the COI Communications chief executive and the joint chairman of DMB&B, had been briefed to rebuild FCB's European network almost from scratch after its alliance with Publicis fell apart.
Reid, who folded the European position into his own following Douglas' departure, said it was the right time to open up the region again, and claimed Hollingsworth was the only person considered for the role.
"Scott has more than demonstrated his ability running our Latin American arm. Now I am looking to tap into his expertise to build up the European network," Reid said.
At the time of Douglas' departure, it was thought that the Bozell/FCB merger would result in Kelly O'Dea, the vice-chairman of Bozell, taking the European job.
