European Union countries are poised to approve a package of emergency measures including windfall profit levies on energy companies and a cut in electricity demand at a meeting of ministers on Friday, a senior EU official said.

"The ministers should hopefully adopt the regulation ... I believe the member states have expressed rather broad support towards the text," the official said, referring to the emergency measures proposed by the European Commission this month.

EU countries' ministers will also debate whether to cap gas prices, although no formal EU proposal for such a price cap is on the table yet, the official said. (Reporting by Kate Abnett; Editing by Alison Williams)
