Harry and Meghan Plead With Followers To help 'Save The Planet' 

The Duke and Duchess of Sussex have asked fans to consider their carbon footprint, just days after new figures show the Royal Household's emissions doubled last year.

Harry and Meghan took to Instagram in the early hours of Monday with a post dedicated to environmental issues and warning that climate change, fossil fuel emissions and plastics are endangering our planet.

But the couple's warning about emissions risks another PR misstep given their globe-trotting lifestyle. And it comes hot on the heels of criticism over their decision to hold baby Archie's christening in private and the revelation of lavish £2.4m taxpayer-funded renovations to Frogmore Cottage.
