The London market jumped in afternoon trading today (30 November) as oil prices surged after Opec agreed a deal to cut production.
The oil cartel announced at its Vienna meeting that its member nations will collectively agree to reduce output by 1.2 million barrels a day to 32.5 million a day, in a bid to boost prices.
The FTSE 100 Index lifted 49.6 points to 6,821.6, as Brent Crude surged more than 7% higher to $50.75 (£40.79, €48), buoying oil stocks after the cartel agreed its first output cut in eight years.
Oil major Royal Dutch Shell rose almost 5% higher, or 98p to 2,129.5p. BP was up over 4%, or 18p to 460.5p.
GKFX chief market analyst James Hughes said: "A failure to finalise a deal would have been terrible for Opec, and would show the oil cartel as impotent in the face of record high output and stubbornly low prices."
In New York the Dow Jones Industrial Average jumped 70 points to a fresh all-time high of 19,191 points in early trading, with energy stocks boosted by reports of the Opec production cut.
