In December of last year, Imran Khan’s sister appealed to King Charles in his position of head of the Commonwealth to speak out on the situation.

According to The Times, Aleema Khanum said: “Pakistan is a member of the Commonwealth of Nations.

“Its key principles in the charter are rule of law, democracy, and human rights. A member nation is busy destroying all three fundamental principles.

“Member states, especially where King Charles is the head of the Commonwealth organisation, don’t speak out against fascism or military dictatorship? What is the point of just organisations then?”

The chairman of the PCB, Mohsin Naqvi, serves as interior minister for the current Pakistan government. The PCB has been contacted for confirmation Naqvi will be present for the audience with the King.

Before the interview with Khan’s sons aired, Sky received a complaint, yet pressed ahead with airing a version of former England captain Michael Atherton’s conversation with Suleiman and Kasim.

In the interview, Suleiman and Kasim expressed concerns over the treatment and security given to their father, as well as criticising the UK government’s response.

Despite the controversy caused by the interview, the Pakistan team returned to the field as scheduled after lunch on the opening day of the second Test.

At the close of play on the second day, Pakistan coach Sarfaraz Ahmed said he and his team did not know about the interview.

“I don’t know anything. I’m just focusing on the match,” said Sarfaraz. “You’re talking about the interview? We don’t know about the interview.”

Speaking to BBC Sport at the conclusion of the second Test, Pakistan captain Babar Azam denied there was ever the threat of not playing, describing the story as “rumours”.

In October, England will tour Pakistan for a one-day tri-series against the home side and Sri Lanka.

It will be England’s fourth separate tour of Pakistan in the past four years following a 17-year gap between visits to the country because of security concerns.
