The FTSE 100 traded higher on Tuesday, extending its winning streak to six sessions, its longest run of gains since May. Melrose was among the strongest performers, rising more than 8% after announcing a $100 million claims programme related to damage at its GKN Aerospace facility in California. A criminal investigation into the incident has been closed, and the site is expected to resume operations next month. Oil prices were only slightly lower after the United States announced new sanctions targeting businesses involved in Iran’s trade network. Treasury Secretary Scott Bessent dubbed the measures Operation Economic Outcast. The sanctions have affected companies in China and Hong Kong but have so far avoided major Chinese financial institutions. Weakness in precious and industrial metals weighed on mining stocks.
