In the run-up to his interview on This Morning, he was seen speeding down London’s River Thames on a boat with a group of Royal Marine soldiers to the studio where the show is filmed.

Grylls jumped out on the shore and sprinted up to the ITV network building, and while presenters Eamonn Holmes and Ruth Langsford hosted the show, viewers saw him climbing a rope outside the studio window behind them.

The TV star then dramatically smashed through the pane and landed on the studio floor in a hail of glass.

As he walked up to the presenters, he exclaimed, “Hey guys, sorry I’m late… I know a good glazier…” while Holmes added, “It’s okay, the insurance will cover it.”
