Venezuela's Opposition-controlled National Assembly declared Nicolas Maduro's presidency illegitimate on Saturday as he was about to begin a second term in office.

“We reaffirm the illegitimacy of Nicolas Maduro,” the assembly's new president Juan Guaido said as he was sworn in at the start of a new legislative session.

“As of January 10, he will be usurping the presidency and consequently this National Assembly is the only legitimate representative of the people.”
