Oct 9 (Reuters) - Gains in financial shares helped London stocks stage a recovery on Wednesday, even as the U.S.-China relationship strained ahead of a critical two-day meeting where the economic powerhouses will try to reach a resolution on trade.
The FTSE 100 edged up 0.1% by 0705 GMT, while the FTSE 250 rose 0.2%.
Just Eat climbed 1.4% to top gainers on the blue-chip bourse after its Dutch rival Takeaway.com reported a surge in quarterly orders.
Among midcaps, GVC added 3%. The Ladbrokes owner boosted its annual core earnings target for the second time in three months on robust demand in its betting shops despite tighter regulation. (Reporting by Muvija M in Bengaluru; Editing by Bernard Orr)
