The Latest on Britain's vote to leave the European Union (all times local):

9:40 a.m.

Top European Union officials have launched a tirade against leaders of the campaign to get Britain out of the EU, saying they devastated the country and then resigned like cowards.

European Commission President Jean-Claude Juncker told EU lawmakers Tuesday that "the Brexit heroes of yesterday are the sad Brexit heroes of today."

He said that "Leave" campaign figureheads Boris Johnson and Nigel Farage "are not patriots. Patriots don't resign when things get difficult, they stay."

European People's Party head Manfred Weber said "we don't know where Mr. Farage is today. Perhaps he's on an island enjoying himself." Farage is an EU lawmaker but was not at the assembly in Strasbourg.

Weber said: "This is completely cowardly."

Liberal bloc leader Guy Verhofstadt likened the resignations to "rats fleeing a sinking ship."
