On Tuesday's AM: An Australian filmmaker is arrested in Cambodia on espionage charges, as his friends call on the Australian Government to help him get a fair trial; UK Prime Minister Theresa May apologises to fellow Tory MPs for her performance during the election campaign; and a shortage of locally produced citrus fruit is looming, with much of our best fruit set to head for lucrative Asian markets. This is an early edition of AM. The complete 30 minute edition will be available for download at 9am.
