- UK stocks ended in the red on Tuesday as a recent recovery rally was sullied by disappointing updates from tobacco bellwether British American Tobacco and homebuilder Bellway.

At 16:30, the benchmark FTSE 100 index had dropped by 2.1%, to 6,339.66 points.

Online women's fashion retailer Sosandar surged 33.7% to 11.7p, even as it warned of a deeper-than-expected annual loss owing to margin contraction.

Sosander also said its revenue for the year through March had more than doubled. In the new financial year, sales had risen 62% over April and May, helping to trim losses.

Personal care distributor Venture Life rallied 13% to 74p on announcing that it would 'comfortably exceed' market expectations for the current year.

Information technology company Aveva climbed 4.7% to £42.1 having held its dividend steady at 29p per share after it nearly doubled annual profit on higher revenue and margins.

Scientific and medical equipment provider Oxford Instruments firmed 2.7% to £12.9 on reporting a 13% rise in annual profit, even as sales weakened in the latter part of its financial year due to the Covid-19 crisis.

Internet of things group Telit Communications gained 1.1% to 127.8p after Britain's Financial Conduct Authority decided to not take enforcement action against the company after probing its market disclosures.

Language and intellectual property support services group RWS fell 4.6% to 597p after it booked a 6.3% fall in first-half profit but held its dividend steady amid a 'limited' impact from the Covid-19 crisis.

RWS also announced that it had acquired Dublin-based machine translation group Iconic Translation Machines for $10m, plus additional deferred consideration of up to $10m in shares, plus Indian counterpart, for $21m.

Self-storage group Big Yellow fell 2.2% to £10.3 as it became one of few companies to up its dividend during the Covid-19 crisis, after stronger sales helped underpin a rise in its annual earnings.

British American Tobacco slipped 3.2% to £30.2 after it downgraded its revenue and earnings guidance, as the Covid-19 pandemic hurt its performance in emerging markets.

British American Tobacco said earnings growth in 2020 would be at a 'mid single-digit' percentage, instead of previous guidance of 'high single-digit' growth.

Bellway dropped 4.7% to £28.2 on warning that home sales activity would be 'severely constrained' until lockdown restrictions were lifted further.
