Bluechip advisers are continuing their aggressive push into the busy Alternative Investment Market (AIM), according to new statistics which see traditional AIM special-ists losing market share.

Norton Rose, Berwin Leighton Paisner (BLP) and Travers Smith were among the firms to take a major chunk of AIM flotations in the past 12 months, beating firms traditionally associated with the sector, such as Nabarro Nathanson, Charles Russell and Lawrence Graham.
