The blue-chip FTSE 100 index rose 0.2% by 0707 GMT, after New York’s S&P 500 notched a record high at the start of a heavy week of earnings from companies including big technology names. Lysol cleaning products maker Reckitt Benckiser jumped 4.4% to the top of FTSE 100 after it raised its full-year forecast as higher sales of cold and flu remedies and price hikes helped it beat analysts’ estimates for third-quarter sales. The domestically focussed mid-cap index inched up 0.1%, with IT services and consulting firm Softcat Plc sliding 6% after reporting full-year earnings. Premier Inn-owner Whitbread climbed 2.8% after reporting a much smaller half-year loss as the travel sector rebounds from the pandemic, and stating it expected a full recovery by 2022.
