On 13 April 1584, after long negotiations, Margaret was allowed to return to her husband's court in Navarre, but she received an icy reception. The situation got worse. In June 1584 her brother Francis died and she missed her most valuable ally. With Alençon's death Henry of Navarre became heir presumptive to the French throne and he was under increased pressure to produce an heir. In 1585, his new lover Diane d'Andouins, nicknamed "La Belle Corisande", pressed the King of Navarre to repudiate Margaret, hoping to be married to him.
