WPP profits on advertising market rebound

Marketing group WPP saw profits in 2010 rise by almost a third to £851m, thanks in part to a rebound in US advertising in the final quarter.

Like-for-like revenue growth - ignoring the effect of acquisitions - hit 8.5% in the last three months of the year.

The results were slightly better than expected, and follow similarly strong upturns at industry rivals Omnicom of the US and Publicis of France.

WPP's Chief Executive Sir Martin Sorrell told the BBC that Western companies are still worried about US debt and Euro sovereign debt crisis.
