The commodity-heavy FTSE 100 gained 0.3% by 0704 GMT, with BP and Royal Dutch Shell climbing 1.4% and 1.6%, respectively, while miners added 0.5%, to be among the top boosts to the index. The domestically focussed mid-cap index rose 0.2%, with travel stocks leading gains with a jump of 1%. Britain was set to scrap tough COVID-19 quarantine requirements for 47 destinations. However, UK mid-caps were set for a fifth straight weekly loss and their worst losing streak in a week since December 2018, as inflation worries weighed. Weir Group fell 6.2% after saying it was the target of an attempted ransomware attack in the second half of September, which impacted its third-quarter profit. Czech trucking services firm Eurowag dropped 10% after it priced its initial public offering on the London Stock Exchange below its previously stated price range.
