As chief editor of the
Chronicle, Doronila earned the ire of President
Ferdinand Marcos for the paper's critical reporting on the administration. On 22 September 1972, he was among the first to be informed of the alleged ambush of Defense Secretary
Juan Ponce Enrile, which was used by Marcos to proclaim
martial law the following day. Newspapers critical of Marcos, including the
Chronicle were shut down, while Doronila was among several journalists arrested and taken into military custody at the
Philippine Constabulary headquarters in
Camp Crame,
Quezon City. He was later released in December after being made to promise not to participate in "anti-national activities," resume work without a military permit from the military, give or participate in any interview with local or foreign media, and was required to report periodically to the military. In 1975, Doronila went into exile in Australia, where he settled in
Melbourne and worked for
The Age. In 1985, he returned to the Philippines to cover the decline and fall of the Marcos regime. ==Later journalistic career==
