King Charles has arrived at Clarence House as the Monarch continues his treatment for cancer.
The monarch appeared to be in a positive mood as he was pictured arriving back at the royal residence late on Tuesday morning.
The 75-year-old is not carrying out public duties while he has treatment but is continuing with behind-the-scenes work on state papers.
While he steps back from official visits, other members of the royal family have stepped up to take on extra duties.

The King was diagnosed with an undisclosed form of cancer following hospital treatment for an enlarged prostate, which was unrelated.
He was treated in the same hospital as the Princess of Wales, who underwent abdominal surgery for an unknown condition in January.
