Grylls said he spoke "from the heart" in backing "Remain" in the 2016 referendum. "At such a time for the UK to retreat, run and cut ourselves loose from Europe, when there are so many challenges on our doorstep, to me just doesn't feel either courageous or kind," he said. "Europe has many flaws, but I also believe the way to help resolve many of those tough issues is from within... I have never been a good quitter and I am so proud of the UK and our values: tolerance, kindness, respect, courage and resilience. This is why I want us to stay together and Remain in Europe." In January 2020, he announced that he had asserted his right to Irish citizenship and had obtained an Irish passport.
