 With opinion at home becoming increasingly detached from political developments in Timor, and more concerned with decolonisation in its African colonies of Angola and Mozambique than with Timor, Lemos Pires' attempts to broker an agreement between the UDT and the other prominent Timorese party, FRETILIN, were undermined, even while he insisted that he was awaiting instructions from the government in Lisbon.Without any possibility of support from Portugal, Lemos Pires maintained his administration for three months until he ordered a withdrawal of staff and left his post for Lisbon on 27 November 1975.Less than two weeks later, on 7 December, Indonesia invaded East Timor, leading to a situation of Indonesian occupation that would last until 1999.
