Prince Harry steps out at US Grand Prix without Meghan Markle

The Duke of Sussex has made a surprise solo visit without Meghan Markle after being branded a “hypocrite” over his climate change stance. See the photos.

Prince Harry has been spotted at a racetrack in Austin, Texas, ahead of the US Grand Prix.

The Duke of Sussex chatted with members of the Mercedes and Red Bull teams gearing up for the Circuit of the Americas.

The royal — who appeared solo without wife Meghan Markle — met up with Christian Horner, the former British racing driver and now Red Bull chief who is married to former Spice Girl Geri Halliwell.

The Duke of Sussex wore a black polo shirt and sunglasses as he went behind the scenes at the event, which ended in a 50th win for Max Verstappen after he held off Lewis Hamilton.

In a shock upset, Hamilton and Charles Leclerc were sensationally disqualified after failing a post-race technical compliance check.

It comes after Prince Harry and Meghan were spotted touching back down in the US following a romantic getaway without their children to the island of Canouan in the Grenadines.

The climate change campaigners were blasted as “hypocrites” for flying to the island on a private jet, just days after speaking about the impact of environmental impacts on mental health.

The Sussexes used a Dassault Falcon 7X jet to fly from New Jersey to Canouan after attending a mental heath summit in New York on October 10, The Mirror reports.

They attended the conference organised by Project Healthy Minds, during which Zak Williams, the son of comedian and actor Robin Williams, said climate change was adversely impacting mental health.
