Cocaine may have been snorted in toilets just yards from the private hospital ward where the Duchess of Cambridge is about to give birth. Tests found traces of the drug in a cistern at St Mary’s in London. Health chiefs have launched an investigation and vowed to take ­immediate action against anyone abusing drugs at the hospital.

The discovery comes as the Royal Family are waiting for Kate’s baby, thought to be a week overdue, to arrive. And scores of diehard fans are camped outside St Mary’s Hospital in Paddington, West London.

A spokeswoman for Imperial College Healthcare NHS Trust said: “We take the safety of our patients and staff extremely seriously. We have 24/7 security cover at all our hospitals with regular patrols and CCTV covering key areas both outside and inside buildings, constantly ­monitored by our security teams. We work closely with police to ­investigate reports thoroughly and take action to ensure the safety of our colleagues, patients and their ­families. If there are signs that a person is abusing substances on one of our sites we will take immediate action to address this.”

The Mirror used drug testing wipes on a surface behind a toilet cistern in a public area of the Cambridge Wing, yards from the Lindo Wing maternity ward at the hospital. It showed positive for the Class A drug.

The screening ­equipment, used by police and the NHS, turns blue to indicate traces of powder/ crack cocaine crystals.
