The FTSE 100 traded slightly lower on Monday, with investors showing limited reaction to a turbulent weekend after the US and Iran agreed to a temporary ceasefire ahead of planned peace talks. Stock-specific corporate news dominated market moves: British American Tobacco fell more than 1% after unveiling a restructuring programme that will reduce its global workforce by around 20%, including 5,500 job cuts and the outsourcing of a further 3,500 roles by the end of the year. In contrast, BT gained 1.4% after securing a new international partnership with US telecoms group Verizon to combine their global enterprise operations. At the same time, broader market focus increasingly turned to politics as Andy Burnham prepared to deliver a speech in Manchester.
