LONDON---A suspicious substance at the British parliament in Westminster was deemed non-hazardous, police said on Monday, in the latest of a string of packages to politicians and royals that have sparked security alerts.
Last month, police investigated a mysterious substance sent to Meghan Markle, fiancee of Prince Harry, in an incident treated as a racist hate crime. White powder was also sent to an office in parliament, but the substances in both cases were found to be harmless.
