TBWA's chairman and creative director, Trevor Beattie, has been pursuing
Silburn since the latter's John West Salmon spot picked up three gold
Lions at the Cannes festival this year.
The appointment will trigger a hunt for a creative partner for Silburn,
who has been handed a free-ranging role across TBWA's account portfolio,
with sign-off on his own work.
"It is often said that you should only hire people who are better than
you," Beattie said. "With Paul, I can go one better. He's the best."
Silburn declined to comment on his decision to leave but Jeremy Pyne,
the managing director of Leith London, denied that its future was
threatened by his departure.
"Money's tight but nothing cataclysmic is about to happen. There's
absolutely no truth in the story that Scotland is about to pull the
plug," he said.
