The FTSE 100 edged higher on Tuesday as falling oil prices boosted sentiment on renewed hopes of a lasting US-Iran peace deal, following an announcement that Israel and Hezbollah would pause hostilities in Lebanon. Mining stocks led the gains in London, with Antofagasta rising more than 6%, Glencore and Anglo American adding over 4%, and Rio Tinto up more than 3%. Banks also strengthened, as HSBC Holdings, Barclays and Standard Chartered gained 2.3%, 3.3% and 2.7% respectively. In contrast, British American Tobacco fell around 3% despite reaffirming full-year guidance and pointing to strong momentum in its Modern Oral and Vapour segments.
