200 complaints of price gouging at the pumps have been received from members of the public by the competition watchdog.
This is up from 83 a week ago after excise duties on petrol and diesel had been cut by 20c and 15c on March 10th.
The number will be revealed at a committee meeting in Leinster House where the CCPC (Consumer and Competition Protection Commission) will update politicians on what they are doing about the alleged unfair price increases.
