Venezuela crisis: Two lawmakers claim Speaker role

Two lawmakers in Venezuela have both declared themselves parliamentary Speaker after a tumultuous day in the country's politics. US-backed opposition leader Juan Guaidó and rival Luis Parra both claimed to be Speaker of the National Assembly on Sunday.
Mr Guaidó, who was aiming to be re-elected to the post, was stopped from entering parliament by national guards.
