The UK's FTSE 100 reached a one-month closing high on Monday, following a global rally driven by Scott Bessent's nomination as U.S. Treasury secretary. However, Kingfisher, the home improvement retailer, saw its shares fall by 13.2% after issuing a profit warning. The FTSE 100 rose 0.4% to its strongest close since October 22, with mining companies Glencore, Anglo American, and Rio Tinto experiencing gains. Meanwhile, the midcap FTSE 250 index advanced 0.8% to reach a near one-month closing peak, and shares in ITV jumped 8.6% after reports of a potential takeover bid.
