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.

Queen Camilla has been holding down the fort since King Charles’ cancer diagnosis in January. 

She has completed 13 official engagements solo since her husband’s condition came to light but is now expected to hand the reigns over to the Prince of Wales and Princess Anne.

The King was diagnosed with an undisclosed form of cancer following hospital treatment for an enlarged prostate earlier this year, 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.

Kensington Palace said last week that Kate would return to royal engagements after Easter.

The Princess of Wales was last pictured attending  a service at St Mary Magdalene Church in Norfolk in January ahead of her planned surgery. 

Most recently, The Queen met Ukraine’s first lady Olena Zelenska at Clarence House on Thursday. 

They were pictured in conversation as they sat in the Garden Room, with their meeting coming just days after the second anniversary of the Russian invasion of Ukraine.

Camilla was also pictured placing her arm behind Ms Zelenska’s back as she guided her along a hallway ahead of their meeting.

Ms Zelenska posted a video on social media showing Camilla greeting her warmly with a kiss on both cheeks and saying: ‘Hello. How very nice to see you.’

She wrote that she was ‘delighted to personally express my gratitude to Her Majesty Queen Camilla, and in her person the whole @RoyalFamily and all people of the UK for supporting (Ukraine) and our IDPs (internally displaced persons).

‘Our values are common – life, freedom, democracy. Thank you for standing up for them together today.’
