WPP says it has seen strong growth in the UK, with constant currency revenues up by nearly 9 per cent. It has also recruited an extra 907 staff in the UK over the last year.
A WPP statement says, ‘2011, the group’s 26th year, was a record year on virtually whatever measure you care to name. The record performance was achieved in difficult circumstances, particularly in the second half of the year.
‘Western-based multinational companies, which today are reputed to be sitting on as much as $2 trillion net cash with relatively unleveraged balance sheets, were still fearful of making mistakes but prepared to invest in capacity and behind brands in fast-growing markets.
‘At the same time, they were also prepared to invest in brands to maintain or increase market share event in slow-growth Western markets.’
WPP has identified three ‘maxi-quadrennial’ events as providing a boost for 2012 – the European Football Championships, the London Olympics and the US presidential elections.
