The Minister for Transport, Mr Cullen, said yesterday he had no intention of resigning over allegations of impropriety in the awarding of public relations contracts.
The Minister said he had yet to speak to Mr Dermot Quigley, the former Revenue chairman who has been charged by the Government with investigating contracts between Ms Monica Leech and departments and offices under Mr Cullen's direct political control.
Speaking to reporters in Dublin at the launch of a campaign on the changeover to metric speed limits, Mr Cullen added: "I have publicly refrained from making any comment now that the inquiries are ongoing only to say that I fully support the inquiries and indeed I look forward to their outcome.
"But I have no intention of resigning in the meantime."
Mr Quigley has already spoken to officials in the Department of Environment, Heritage and Local Government and the Office of Public Works.
He has been asked to complete his work before the end of this month.
The contracts with Ms Leech, a close political associate of Mr Cullen, are also under scrutiny by the Standards in Public Office Commission.
When Mr Cullen was appointed Minister for the Environment in 2002, Ms Leech was engaged to provide PR advice. She has received some €300,000 from the Department.
