Activist investor Elliott Advisors ratcheted up the pressure on Wednesday, saying it will attempt to oust AkzoNobel's managers if the company fails to start talks with PPG. Elliott, which holds more than a 3% stake, said "most shareholders" wanted the company to engage with PPG and threatened to call an extraordinary general meeting (EGM) where investors could vote to remove managers if more than half the issued capital is represented. Top 20 shareholders Columbia Threadneedle and Henderson are also said to be pressing for talks to begin.
