[5] While appreciating Mintoff's social reforms, including the separation of Church and State, Briguglio considered his economic policies to be based on obsolete yet widespread assumptions that government would decide better than the private sector.
[6] Briguglio later wrote a book (L-Elementi Kriminali w Vjolenti Fi Hdan il-Partit Laburista, 1986) about how the violent and criminal elements in the Labour Party were not being controlled by Mintoff,[3] and stated that the merger of the party and the union was key to control industrial conflict given Mintoff's wage suppression policy.
[7][4] Briguglio later co-founded and was first general secretary of the Maltese Democratic Party (PDM),[1] with which he contested the 1987 elections, obtaining a total of 380 votes and zero seats.
The work of the IPCC, including the contributions of many scientists, was recognised by the joint award of the 2007 Nobel Peace Prize.
[15] Briguglio has acted as consultant to several international organisations including the UNDESA, UNEP, United Nations Development Program, the United Nations Conference on Trade and Development (UNCTAD), World Bank, the Commonwealth Secretariat,[16] SOPAC and CARICOM on matters related to the economies of small states.
His son-in-law Stefano Moncada succeeded him as Director of the University of Malta's Islands and Small States Institute in 2020.
