EU leaders have been meeting today to discuss European security and the fuel crisis caused by the war in Ukraine.
The Taoiseach is in Versailles for the informal EU summit before he heads to London later.
Micheál Martin wants more flexibility on the tax on fuel in the hopes something can be done to cut VAT on petrol and diesel.
Finance Minister and President of the Eurogroup Paschal Donohoe has also joined criticism of potential price gouging on fuel:
"I fully stand by the Taoiseach and his comments earlier on in the week. We all need to play our part at this extraordinary. We will work with the suppliers in the coming weeks and months and beyond that even to ensure that we maintain security of supply, but also that we all do what we can to ensure that the measures that I announced are implemented."
