The railway signalman had a leg amputated before he died at Harefield Hospital near Uxbridge on Saturday. His wife Sarah, 42, described him as a "fantastic father" to Matthew, 12, and Lauren, 14. Mrs Fleming said: "I was with Stewart when the GP called the hospital. He typed us a letter and told us to go to A&E and hand this letter over and that Stewart should be treated immediately. But when we got to A&E it was full to bursting. I walked to the front with the letter and told them what the GP had said, but I was just told to go to the back of the queue."
