The unstable situation continued under Dorji's successor as acting lonchen, his brother Lhendup Dorji, and for a time under the Druk Gyalpo's brother, Namgyal Wangchuck, as head of the army. According to some sources, a power struggle ensued between pro-Wangchuck loyalists and "modernist" Dorji supporters. The main issue was not an end to or lessening of the power of the monarchy but "full freedom from Indian interference." Other observers believe the 1964 crisis was not so much a policy struggle as competition for influence on the palace between the Dorji family and the Druk Gyalpo's Tibetan consort, Yanki, and her father. Lhendup Dorji had earlier threatened to kill Yanki—his sister's rival—and ordered her arrest when, fearing for her life and that of her 2-year-old son by the Druk Gyalpo, she sought refuge in India during the political crisis. Lhendup also incurred the disapproval of the Druk Gyalpo by seeking to become sole regent of the kingdom after his brother's death, eliminating the Queen and the king's brother. Before returning to Bhutan from Switzerland, Jigme Dorji met with the Indian Secretary General and Foreign Secretary in Calcutta who offered Indian support, including paratroopers if necessary, to help the Druk Gyalpo restore order in the kingdom. Unable to regain the Druk Gyalpo's trust, Lhendup fled to London, while other supporters in the military and government fled to Nepal and Calcutta. Afterwards, in concurrence of the National Assembly, Lhendup Dorji and other family members were exiled in 1965. However, the exiles continued their attacks on the Druk Gyalpo and India, worsening relations between India and China. The tense political situation continued and in July 1965 there was an assassination attempt on the Druk Gyalpo. The Dorjis were not implicated in the attempt—which was described as a "private matter"—and the would-be assassins were pardoned by the Druk Gyalpo.
