The Secretary General of the Department of Public Expenditure and Reform, Robert Watt, is to be asked to appear before the Oireachtas Communications Committee next Wednesday as part of its investigation into the National Broadband Plan.
Committee Chairman, Fianna Fáil's Timmy Dooley, said the committee has agreed to carry out an investigation which will be completed within eight weeks. It will also look at the best means of rolling out rural broadband.
RTÉ News understands that the committee is to write to Mr Watt who to request his attendance at its first meeting on the issue next Wednesday.
Mr Watt had warned the Government that the plan posed a great financial risk and provided questionable benefits.
Documents released by the Government last week show that Mr Watt even went so far as to call for the process to be cancelled.
