According to results released last week, WPP made pre-tax profits of £427 million, up 19.4 per cent year on year. In July, Publicis reported pre-tax profit growth of 17.4 per cent to €446 million (£377.5 million).
Both companies attribute the growth to investment in digital and the fast-growing markets of South America and Asia.
Sir Martin Sorrell, the chief executive of WPP, told Campaign: “Our performance was led geographically by Asia-Pacific, Latin America, Africa and the Middle East, and Central and Eastern Europe, and improved performance in the US and the UK.
