The blue-chip FTSE 100 index declined 1% at 0710 GMT, with miners Rio Tinto, Anglo American and BHP Group falling between 1.2% and 2.3%. Industrial and precious metal miners fell about 1% each, and banks fell 1.5%. The domestically focussed mid-cap index declined 0.8%, with capital goods stocks among the worst performers. Payments specialist Equiniti, which is being bought by New York-based company Siris Capital, could face some job cuts once the deal is closed, the private equity firm said late on Monday. Its shares rose 0.5%. On the macro front, UK’s labour market showed signs of further recovery as employers added a record-high 207,000 staff to their payrolls in September and separate data showed UK’s unemployment rate fell to 4.5% in the three months to August, reinforcing bets for a sooner Bank of England rate hike.
