According to a report in The Observer newspaper the WPP chief will herald an end of the worst advertising recession the industry has ever suffered in another sign that the recovery is picking up speed.
Sir Martin is usually reluctant to be overly upbeat when predicting the industry's fortunes and to date has shied away from making any sweeping suggestions that the recession is over.
Sir Martin and many other observers had gingerly pointed to 2004 being a better year as the industry benefits from spending around the US Presidential elections, the Euro 2004 football championships and the Olympics.
Last month Sir Martin said that telecoms, technology and financial services companies had started spending again on ads after three years of recession.
However, the paper quotes sources close to the company that say Sir Martin will take a more bullish stance. It says Lehman Brothers is predicting WPP will post pre-tax profits of 拢454m on revenues of 拢4.04bn.
Last week saw WPP shares soar after rival Omnicom Group posted a 10% rise in quarterly profits, giving further signs that the recovery is gaining momentum.
