Sir Brian Souter was one of many today to pay tribute to Bob Crow, who sadly passed away on the 11th of March 2014. Amongst those paying tribute were London mayor Boris Johnson, Labour leader Ed Milliband and Prime Minister David Cameron.
Speaking to the BBC, Sir Brian Souter praised Crow on his hard work and contribution to the transport sector:
"Bob Crow was a passionate advocate for the country's railway.
"He worked tirelessly on behalf of his members and shared our focus on the critical importance of safety.
"His views on transport policy may often have been at odds with our own, but he was a man who commanded respect across the sector for his strength of belief in the causes he pursued."
