British Prime Minister Theresa May has been urged to avoid a no-deal Brexit by Japanese Prime Minister Shinzo Abe.

May has secured an exit agreement with the EU but now faces an uphill struggle to get it approved by a deeply divided British parliament.

"I would like to take this opportunity to express my tribute to your leadership in realizing the withdrawal agreement as well as the EU's agreement on the political declaration," Abe said on Saturday in Beunos Aires.

"Also, I would like to once again ask for your support to avoid no deal as well as to ensure transparency, predictability as well as legal stability in the Brexit process."
