Previously unseen footage from Princess Diana’s landmark 1997 visit to Angola has been unveiled, revealing the princess’s determination to confront political criticism despite objections from her own team.The archive material, released on Wednesday as part of the broadcaster’s Reporting History series, captured Diana during a sit-down with journalists in January 1997, when she travelled to the war-torn country to campaign against landmines.When then-Africa correspondent Steve Scott asked whether he could pose a question about “the political role,” Diana responded: “I’d have thought that was the most important question out of the two. I’d go for that one.”Her team attempted to intervene, with someone off-camera urging: “No, not the political one, you don’t mean the political one.”Princess Diana seen disagreeing with her advisers in unearthed footage | ITV NEWSThe princess pushed back, making clear she wished to address the matter directly.Diana’s Angola trip had ignited fierce controversy, with the Conservative Government and sections of the tabloid press accusing her of endorsing Labour Party policy on the issue.In the newly released footage by ITV, the princess dismissed such criticism as irrelevant to her mission.”I saw it merely as a distraction as I’m not a political figure, I’m a humanitarian figure.
