Skinner previously expressed regret about participating in the show, stating he "never fitted the bill" and wished he had not taken part.
His time on the programme was marked by controversy, including receiving death threats after meeting US vice president JD Vance.
He also faced criticism for social media posts about patriotism and London's safety, and admitted to cheating on his wife shortly after joining Strictly.
His professional dance partner, Amy Dowden, who recently underwent a second mastectomy, will be present at the final and had previously supported Skinner amidst backlash.
