Brexit deal 'best possible' and 'not renegotiable': Macron

French President Emmanuel Macron said Tuesday the Brexit deal is the "best agreement possible and is not renegotiable", as Britain's premier pushed to reopen talks with Brussels. Macron's comments during a summit in Cyprus came as Prime Minister Theresa May appealed to British lawmakers to give her a mandate to renegotiate, after parliament rejected an accord reached with the European Union. Macron urged the British government to "promptly" lay out to EU chief negotiator Michel Barnier "the next steps that will prevent an exit without an agreement, which nobody wants but for which we must all prepare ourselves".
