Updated 4.40pm - A suspicious substance found at the British parliament in Westminster on Monday afternoon was not hazardous, UK police have said.

The substance was found in a package at the Norman Shaw Building, where many lawmakers have their offices, on the parliamentary estate.

Two people were hospitalised as a precaution.  

There was no evacuation, but the affected area was cordoned off. 

Last month, police investigated white powder sent to an office in parliament, which was later found to be harmless.
