Lord Blunkett has called for an urgent review into what he described as "death trap" Tube platforms after he was injured falling into a gap as he boarded a train at Westminster station.
It happened as the Labour Peer, who is blind, slipped while getting on to a District line train with his guide dog, last month. He wants Transport for London (TfL) to do more to ensure visually impaired people are kept safe.
"I didn't fully know what had happened. I felt enormous pain in both my legs; they were bruised and grazed," the 77-year-old former home secretary and health secretary wrote in the Sun on Sunday.
London Underground said it was "extremely sorry" that Lord Blunkett was injured and will be meeting with him to ensure that lessons are learned from the incident.
