Shareholders had to sit through almost two hours of presentations before they are allowed to vote on Sir Martin Sorrell’s proposed £6.8 million remuneration. Representatives from WPP’s key new markets – Brazil, Russia, India and China – enthused about their growth prospects and Sorrell charted the company’s 35% compound annual revenue growth rate since he founded it in 1985. But this sales pitch from the world’s largest advertising group, by sales and market value, was in vain: most investors had already voted by proxy before Wednesday’s meeting began.
