UK oil explorer Regal Petroleum has backed an improved takeover bid from Energees Investments, which came on the back of a rival bid from a Ukrainian billionaire.
The offer from Energees values its proposed 70 per cent stake in Ukraine-focused Regal at around £85 million.
Energees is the main holding company of Ukraine's Smart Holding Group.
The revised offer comes following a rival proposal from Cyprus-based Heamoor and oil explorer Geo-Alliance. Both Heamoor and Geo-Alliance are controlled by the Ukrainian billionaire Victor Pinchuk.
