Billionaire retailer Solomon Lew has threatened to requisition an extraordinary general meeting of Myer shareholders in a bid to overthrow the board and appoint his own slate of directors.

Mr Lew’s listed investment company, Premier Investments, which this week outlaid another $16.4 million to lift its stake in Myer to 15.8 per cent from 10.8 per cent, said it had instructed lawyers Arnold Bloch Leibler to request a copy of Myer’s share register and retained a proxy solicitation firm, Morrow Sodali, to collect proxy votes from investors ahead of an EGM.
