The Philippine immigration bureau has again ordered the deportation of Australian nun Sister Patricia Fox who has angered the president by joining anti-government rallies.

Her lawyers have called Thursday’s move “persecution” and say they will appeal.

The Bureau of Immigration also wants to prohibit Sister Fox from returning to the country for violating the terms of her missionary visa.

Justice Secretary Menardo Guevarra said Sister Fox’s deportation would not be enforced while she appeals.

Last month, Guevarra revoked the Bureau of Immigration’s cancellation of Sister Fox’s missionary visa but allowed the agency to proceed with efforts to deport her for another alleged offence.

Sister Fox, 71, is a co-ordinator of a Roman Catholic order of nuns Our Lady of Sion and has worked for the poor in the Philippines for about 27 years.

She advocates for human rights and workers’ welfare and has joined rallies against President Rodrigo Duterte and his government, which has been criticised for stifling dissent and for its brutal war on illegal drugs in which thousands of mostly poor suspects have died.

The immigration bureau said Sister Fox violated her missionary visa by venturing far beyond her community in suburban Quezon city in metropolitan Manila and interfered in domestic politics by joining protests and news conferences that tackled “political and human rights issues against the government”.

“Her presence in the country poses a risk to public interest,” it said.

President Duterte has backed the immigration bureau’s effort to expel Sister Fox.

Sister Fox’s lawyers said they were utterly dismayed and would appeal to fight “this kind of persecution”.

“Helping the poor is not a risk to public interest, peace or order. In fact, the government must recognise her selfless service to the oppressed sectors of this society,” her lawyers said in a statement.

The immigration bureau, however, said that allowing Sister Fox to join political rallies and other such activities would allow other aliens to do so as well.

Mr Duterte has been hyper sensitive to criticisms especially by foreigners, who he says have no right to meddle in his country’s domestic affairs. His bloody anti-drug crackdown has left thousands of suspects dead and alarmed human rights groups and Western governments.

His administration barred a critical Italian politician, Giacomo Filibeck, from entering the Philippines in April.
