Lord Mackinlay spoke of the challenges he has faced in his rehabilitation, telling the BBC he had “struggled to get doors open, get my seatbelt on, or even get my train ticket from my pocket”.
He made an emotional return to the House of Commons in May, where he received a standing ovation in the chamber.
He said it made him feel like “Russell Crowe in Gladiator” calling it an “amazing moment” that he would not forget.
At the time, he called on the then prime minister, Rishi Sunak, to speed up and fund the care provided to those who had survived sepsis.
Speaking of his ambition for the Lords, he said he hoped he could “make a difference” and warned colleagues he would be “loud” as he continued to campaign for better after care.
He said: “I know it’s costly but I want people to be given digital replacements”.
