UK passport warning issued for flights to France, Greece, Italy and Spain

British citizens are urged to perform two critical passport checks before travelling to France, Greece, Italy, and Spain, as over one million UK passports may not meet entry requirements. Simultaneously, France and Spain are preparing for their fourth summer heatwave, with temperatures expected to reach the low 40s Celsius. Authorities in the Gironde and Madrid regions fear these extreme temperatures could hinder efforts to contain destructive wildfires, despite recent progress in controlling several flare-ups.
