UK PM Burnham says may rejoin EU; France, Spain say 'welcome back'

British Prime Minister Andy Burnham has suggested the UK need to rethink its relationship with the European Union. He remarked that Brexit has not lived up to its commitment of regaining control, particularly over immigration matters. European leaders remain open to Britain's return, as polls reflect some public support; nevertheless, any formal talks would be postponed until after the next election, likely influenced by changing public sentiments.
