Doctor Alex George has paid an emotional tribute to his younger brother Llyr after he was laid to rest yesterday.

The youngster lost his battle with mental health issues last month just weeks before he was due to follow in his big brother's footsteps by starting medical school.

Llyr's funeral was held yesterday and today Alex, 30, updated his followers on the toughest day of his life and made a promise to his brother.

Posting a picture of the pair together, Alex wrote on Instagram: "Yesterday I said goodbye to my little brother Llŷr. It was the hardest day of my life. Except it wasn't goodbye. Llŷr, your dream was to become a doctor, you will live that dream. Every patient I see, we will do it together, you and I ❤️

"Your favorite passion is cars, every time I am out driving, I know you will be there laughing and smiling with me. I love you so much Llŷr, you are always with me, my boy ❤️"
