Prince Harry and his father Prince Charles are reportedly planning to take a walk together in Windsor to view floral tributes left for Prince Philip.

Their relationship has been strained since Harry and his wife Meghan moved to the US and gave a television interview to Oprah Winfrey in which they claimed a family member had expressed concern about the skin colour of their unborn son.

Harry is scheduled to fly back to the US imminently but it has been suggested he might delay his return so he can be with Queen Elizabeth II, his grandmother, when she marks her 95th birthday on Wednesday.

Harry has been self-isolating following his return to the UK, staying at Frogmore Cottage within the grounds of Windsor Castle, about 40 kilometres west of London.

He was given compassionate leave on Saturday to attend his grandfather's funeral.

It was the first time he has been seen publicly with royal relatives since he left the UK.

Floral tributes placed outside the castle grounds during the funeral were taken inside the walls for the royal family to view.

"There has been talk that Charles will walk around Windsor with Harry to look at some of the tributes and spend some time together," the Mail On Sunday quoted a royal source as saying.

Officials at Clarence House, Prince Charles' residence, told The National there would be no comment on any "private time" the pair have together.

Prince Harry was reunited with his brother Prince William and his father for two hours after the funeral.

The three met up away from the cameras following Saturday’s televised service.

Harry was seen chatting with his brother as the pair left the funeral with Prince William's wife, Kate.

A royal insider told The Sun that their discussion was the "first step" to a mending of their relationship that "Prince Philip would have wished for".

The queen and her family paid their last respects to Prince Philip at a funeral on Saturday.

He died at Windsor Castle aged 99 after a month of hospital treatment for a heart condition and an infection.

His coffin, covered with his personal standard, a wreath, his sword and naval cap, was placed on a Land Rover that he had adapted for the occasion.

The queen led the funeral procession as her children and grandchildren walked behind the hearse.

Prince William and Prince Harry, who as young boys walked behind their mother Diana’s coffin at her funeral in 1997, followed the procession on foot, but not side by side.

Between them was their cousin, Princess Anne’s son Peter Phillips.

Prince William, Harry's elder brother, was prompted to deny last month that the royals were racist after the comments made during the Oprah Winfrey interview.

“We are very much not a racist family,” he said.
