Attorney General Menachem Mazuz is expected to make a decision after the Sukkot holiday on whether to launch a new criminal investigation into Prime Minister Ehud Olmert.

The investigation would focus on several affairs involving the prime minister. In a letter sent Sunday to MK Ophir Pines-Paz, Mazuz aide Ran Nizri wrote, "We will make every effort to speed up the handling of these cases, and we believe that the attorney general will soon make a decision on the various affairs."

One of the affairs being considered by involves suspicions that Olmert gave special consideration to a company represented by his friend and former law partner, Uri Messer, in grant allocations by the Industry, Trade, and Labor Ministry's Investment Center.
