Welsh Liberal Democrat Leader Jane Dodds said of the latest energy firm profit news: "It is absolutely abhorrent that the Conservative Government has not taken stronger action against companies like Shell who have posted their largest profits in 115 years, profiteering off the Russian invasion of Ukraine.
The Senedd member continued, "While these companies take in obscene profits, everyday families and local businesses are struggling to stay afloat.
"If the Conservatives implemented a real windfall tax and closed loopholes the extra funding could be used to extend support for these businesses which is due to end in April.
"Rishi Sunak failed to take proper action against energy companies when he was Chancellor, now he is failing again as Prime Minister. The Conservatives must urgently change track and tax the oil and gas companies properly and at the very least ensure that energy bills don't rise yet again in April."
