The BBC reports:
A glass roof panel has cracked in the atrium at Portcullis House – a £235m annexe to the House of Commons in Westminster.
Therese Coffey, Conservative MP for Suffolk Coastal, tweeted: “Great deal of excitement in Portcullis Atrium as a roof panel shatters.”
Security guards have cleared the area beneath the panel in case it comes down.
