The FTSE 100 surged to an almost two-month high as commodities pushed the market higher, more than offsetting slumps by four major firms hit by profit warnings.
London's top flight closed 61.09 points higher at 7,351.08 at the end of trading on Thursday.
The London markets jumped on trade optimism, despite heavy falls from blue-chip giants Imperial Brands, Pearson, IAG and Carnival.
Connor Campbell, financial analyst at Spreadex, said: "Putting all the markets to shame was the FTSE, which let rip with a surge, leaving it near an eight-week peak.
"Keeping the FTSE buzzing was its commodity sector, obviously influenced by Trump's trade deal rumours, alongside the continued misery of sterling."
The FTSE 100's heaviest faller was Pearson, which plummeted after the education publisher warned that students are turning to online and digital resources faster than bosses expected - hitting profits.
These are now expected to be at the bottom end of expectations between £590 million and £640 million.
It dragged shares lower, falling 120.8p to 740p at the close of play.
