A Sinn Fein worker has asked the fraud squad to investigate whether Taoiseach Brian Cowen withheld information on banks before the 440 billion euro deposit guarantee was brought in.
Eoin O Broin also asked gardai to launch the probe into Finance Minister Brian Lenihan and the then chief executives and chairmen of Bank of Ireland and Allied Irish Bank.
The west Dublin representative said there was a series of meetings between Government and heads of the banks in the run-up to the introduction of the scheme in September 2008.
"I have today asked the Garda to investigate whether or not Brian Cowen and Brian Lenihan deliberately withheld information from the Dail regarding the insolvency of Anglo Irish Bank or whether or not the officials from Bank of Ireland and Allied Irish Bank withheld information from Cowen and Lenihan in meetings before the enactment of the bank guarantee scheme," Mr O Broin said.
The complaint was made under Section 6 of the Criminal Justice Act.
