The FTSE 100 index closed lower in the last session, falling 0.34% to 10,494.06 points. This decline was primarily driven by a global sell-off in technology stocks, falling crude oil prices, and ongoing geopolitical tensions in the Middle East, including an Iranian strike on a cargo vessel. Energy and other commodity-related stocks, such as Shell and BP, faced headwinds due to the drop in oil prices and a stronger US dollar.

The FTSE 250 index closed lower in the last session, shedding 0.24% to finish at 23,104.93 points. This decline was primarily driven by a global sell-off in technology stocks amid AI uncertainty, falling commodity prices which impacted energy giants like Shell and BP, and ongoing geopolitical tensions in the Middle East. Additionally, the UK's political landscape, with the resignation of Keir Starmer and anticipation surrounding Andy Burnham's fiscal policies, contributed to the market's backdrop.
