What's really going on in Queen Letizia's marriage? 20th anniversary of her wedding to King Felipe is marred by ex brother-in-law who continues to claim they had an affair - and is planning a TV serie

A couple's 20th wedding anniversary should be a delightful occasion - but for the Spanish King and Queen, it's perhaps not as joyful as it could've been seven months ago, before bombshell claims of an 'affair' rocked the monarchy. King Felipe, 56, and Queen Letizia, 51, will mark their significant milestone on 22 May, and have already shared sweet family photographs alongside their daughters Princesses Leonor, 18, and Sofia, 17, to celebrate The 'affair' rumours first rocked the Spanish monarchy in November after Del Burgo contributed to a tell-all book about the Queen of Spain, titled Letizia y Yo by journalist Jaime Peñafiel. Del Burgo claims he was going to propose to the newsreader until she announced she had met King Felipe Taking to X, formerly Twitter, at the start of May, the lawyer also revealed his plans to produce an eight-part TV series, detailing the 'truth' about his bombshell claims Contributing to Peñafiel's Letizia y Yo, Del Burgo claims in the book that he and Letizia were dating when she met Felipe and were still romantically involved after her wedding to the Spanish King 20 years ago.
