UK’s FTSE 100 hit a three-week high on Monday, lifted by oil giants as crude prices rallied following a surprise output cut by OPEC+, while theatre chain Cineworld neared record lows as it failed to find a buyer for its US, UK and Ireland businesses.

Energy heavyweights Shell Plc and BP Plc advanced over 4% each as crude oil prices jumped more than 5% following an unexpected output cut over the weekend by the Organization of the Petroleum Exporting Countries(OPEC) and its allies.

The broader energy sector was up 4.3%, on course for its biggest daily gain in more than four months.

The export-oriented FTSE 100 rose 0.5%, kicking off the new quarter with gains, as the pound slipped. The domestically-oriented FTSE 250 was flat, as of 0721 GMT.
