IAG slid 3.6% after it declined to give a profit forecast for the year due to COVID-19, but said its summer capacity would rise to 45% from 22% in the previous quarter. The blue-chip FTSE 100 lost 1.0%, with travel stocks leading the losses, while miners Rio Tinto , Anglo American, and Glencore were the top drags. Glencore fell 2.7% after it reported lower production data for nickel, lead and coal in the first-half, but raised expectations for its trading division. The mid-cap index fell 0.7% Among earnings, global education group Pearson slipped 1.3% even after it reported a better-than-expected rebound in first-half profit and a 17% jump in underlying sales, helping it raise its dividend.
