Staff at Finsbury, the UK financial public relations firm, could share as much as £60m (€96m) over the next four years after being bought out by WPP, the acquisitive UK media group.

The three partners at Finsbury, Roland Rudd, a former financial journalist, Rupert Younger and James Murgatroyd are the only three shareholders in Finsbury, and will benefit most from the deal. But it is understood that a portion of the equity will be reallocated to existing and new employees.
