Prince Harry arrives in the UK to see his father after King Charles' cancer announcement

Prince Harry arrived in the U.K. on Tuesday to see his father after it was announced that King Charles III received a cancer diagnosis. 

The prince was seen leaving London's Heathrow Airport in an SUV going to his father's Clarence House residence, according to CBS News.

His wife, Meghan, the Duchess of Sussex did not appear to be with him. 

The king informed Harry and brother William, the Prince of Wales, of his diagnosis before the announcement was public. 

Charles, 75, started cancer treatment Monday and his doctors advised him to postpone public duties at this time, but the monarch of the United Kingdom will continue to conduct official business as usual, officials said. 

The palace did not specify what form of cancer Charles was diagnosed with nor the stage it is in.
