CARACAS (Reuters) - Venezuela's Congress on Tuesday requested a criminal investigation of opposition deputy Maria Corina Machado for crimes including treason in relation to her involvement in anti-government protests that have left dozens dead.

Machado, a 46-year-old engineer, has been one of the most visible leaders in six weeks of opposition demonstrations against socialist President Nicolas Maduro that have unleashed the country's worst unrest in a decade.
