It was put up from €1.99 cent to €2.14.
Fianna Fail says it's unacceptable that some petrol stations are profiteering on the back of a barbaric invasion of Ukraine.
Laois Offaly TD Barry Cowen says he spoke to a member of staff today who received an instruction to increase the price of diesel from €1.99 cent to €2.14 yesterday.
It then fell by 15 cent this morning after the reduction in excise was introduced by the Government at midnight.
A number of other deputies are also calling on the Competition and Consumer Protection Commission to investigate allegations of price gouging by fuel companies.
Deputy Cowen says he feels sorry for the hard working staff who are being used as pawns:
