Prime Minister Boris Johnson has thrust Britain into a constitutional crisis by breaking the law he set for pandemic restrictions, effectively "shredding the ministerial code", the country's leading constitutional expert said on Sunday.
Peter Hennessy, a historian and member of the upper house of parliament, said Johnson had become "the great debaser in modern times of decency in public and political life" after he was fined by police for attending a social gathering in Downing Street while lockdown restrictions were in place.
