The ECB were in contact with the Foreign Office on the first day of the second Test at Lord’s as fears grew that Pakistan might not emerge after lunch in protest at Sky’s interview with the sons of imprisoned former prime minister Imran Khan.Daily Mail Sport understands that chief executive Richard Gould spoke to officials to ask for diplomatic assistance in case the Pakistan Cricket Board carried out their threat to delay the restart.Pakistani disquiet over the broadcasting of Mike Atherton’s interview with Suleiman and Kasim Khan, filmed on Wednesday, had begun before the lunch interval once Sky’s plans became clear.The 73-year-old Imran, who captained Pakistan to World Cup glory in 1992 before becoming the country’s prime minister in 2018, has been in prison for the last three years on corruption charges which his supporters believe have been trumped up by the government. His sons told Atherton they fear for his life. Imran Khan’s sons Suleiman and Kasim were interviewed by Michael Atherton for Sky Sports at lunch on day one of the second Test at Lord’s 73-year-old Imran, who captained Pakistan to World Cup glory in 1992 before becoming the country’s prime minister in 2018, has been in prison for the last three years on corruption chargesWith Pakistan’s interior minister Mohsin Naqvi doubling up as chairman of the Pakistan Cricket Board, sport and politics in the country have become hard to disentangle – hence Thursday’s threat to derail the first Test once it became clear Imran’s sons would be criticising government policy.Fearing a repeat of the financially ruinous Oval Test of 2006, when Pakistan captain Inzamam-ul-Haq refused to lead his players back out after tea on the fourth day because his bowlers had been accused of ball-tampering, Gould contacted the Foreign Office to appeal for help if the worst-case scenario ensued.In the event, Sky delayed broadcasting the 18-minute interview until the second half of the 40-minute interval, by which time Pakistan agitation had cooled and the players were ready to resume.The interview was quickly replaced by adverts on Pakistan TV, which has been taking the Sky feed for this game, while the PCB have not responded to requests for comment.
