TV presenter Andrew Marr has made his first small screen appearance since suffering a stroke earlier this year – and admitted he was ‘lucky to be alive’.

The 53-year-old, who appeared as a guest on his own Sunday morning show, said he had been working too hard in the months leading up to his illness – and had already suffered two previous strokes without realising.

“I had a major stroke – I’m frankly lucky to be alive,” Andrew told the show’s guest host Sophie Raworth,

“I had been heavily overworking – mostly my own fault – in the year before that. I’d had two minor strokes it turned out, in that year, which I hadn’t noticed.”

He added that a bout of over-exercise had also been partly to blame.

“I went onto a rowing machine and gave it everything I had, and had a strange feeling afterwards – a blinding headache, and flashes of light – served out the family meal, went to bed, woke up the next morning lying on the floor unable to move,” he recalled.

And he jokingly warned viewers to be wary of exercise, adding: “Beware rowing machines, or at least beware being too enthusiastic on rowing machines would be my message to the nation.”

Andrew – who also revealed that he was undergoing physiotherapy to help with his walking, said he was planning to return to work once his mobility improved.

“I’m certainly coming back,” he said. “I’ve got a lot more to say about it all, but I’m going to wait until I’ve gone through the physio to do so.”
