Colonel Tom Moore's grandson Max went viral today after appearing on Good Morning Britain to mark the war veteran's 100th birthday.

Moore has now raised more than £31 million for the NHS by walking laps of his back garden and has been duly rewarded with a promotion from Captain to Colonel by the Army.

GMB has closely followed Moore's story over the last few weeks and today broadcast an interview with his 20-year-old grandson Max, prompting a series of thirsty tweets from viewers.

One wrote: "side note, captain Tom Moore's grandson Max is a weapon. good morning to you too!"

Moore earlier received special birthday greetings from The Queen and Prime Minister Boris Johnson.
