London - Britain's Supreme Court is scheduled to begin hearing legal arguments on Tuesday against Prime Minister Boris Johnson's suspension of parliament, amid accusations that Johnson wants to reduce scrutiny of his Brexit plans.
The hearing is expected to last three days, with evidence from three separate appeals in England, Scotland and Northern Ireland.
Johnson has rejected calls to recall parliament, insisting he did not mislead Queen Elizabeth II when he asked her to approve its prorogation, or suspension.
He said he requested the suspension to allow him to present a programme for improvements to health services, policing and other "people's priorities" to a new parliamentary session.
Anti-Brexit legal activist Gina Miller, the lead plaintiff in the English case, said the issue at stake is "so much more important even than Brexit."
