A dozen countries working on ways to end Venezuela's crisis on Thursday gave their backing to opposition leader Juan Guaido as parliamentary speaker, rejecting the claims of a rival.

The number of Venezuelans fleeing economic devastation at home under Maduro is likely to soar from 4.5 million currently to 6.5 million next year.
