Siteserve's share register for the period before its sale is to be made public from today.
It comes after it emerged the company, which was sold to a Denis O'Brien-owned firm Millington in 2012 at a loss of €100m to the tax payer, saw a sharp rise in shares swapping hands in the month before the first bids for the firm were received by IBRC.
Yesterday, Fianna Fáil leader Micháel Martin said the trading activity at Siteserv before its sale raised "serious questions".
According to the Irish Independent, Siteserv liquidator Kieran Wallace is to make the document available on request from as early as this morning.
