Greek Prime Minister Kyriakos Mitsotakis urged Europe to quickly find a way to deal with rising gas and electricity prices that have sapped household incomes, or face the risk of seeing populist forces on the continent again, Reuters reported.

Mitsotakis urged Europe to agree on a joint response to rising energy prices.

It is not appropriate to place this burden on our citizens, especially when we are talking about natural gas prices that do not reflect the fundamentals of supply and demand, he said during a meeting with European Energy Commissioner Kadri Simson in Athens.

European governments are rushing to build up a buffer stock of gas until next winter to help deal with potential supply disruptions from Russia, which provides 40% of the EU's gas needs.

The European Commission last month proposed legislation requiring EU countries to fill their gas storage facilities by 80% this year.

Greek Energy Minister Kostas Skrekas said the Greek gas network operator will receive a new floating tank in the coming weeks to increase the storage capacity of Greece's only liquefied natural gas terminal.
