Campaigning Sarawak-born British journalist Clare Rewcastle Brown uncovered the corruption and theft of $7 billion which triggered the downfall and arrest of the former Malaysian Prime Minister Najib Razak and exposed the 1MDB Development Fund scandal. Her exposé on state investment fund 1MDB revealed grand kleptocracy by the Malaysian Prime Minister that rocked the global financial community in the largest theft ever investigated globally.

In 2010, she started Sarawak Report and short-wave broadcaster Radio Free Sarawak - operated in secret from London, and later Bali, Brunei and Sarawak itself. The Malaysian government tried to arrest her for “activities detrimental to Parliamentary democracy” and banned her website. Malaysia issued a warrant for her arrest in 2015 and requested INTERPOL place her on the international Red Notice list, a request INTERPOL rejected. Following the defeat of Najib in the May 9^th 2018 election, Malaysia rescinded the warrant.
