Quote:A leading critic of Philippine President Rodrigo Duterte, Senator Leila de Lima, has been arrested on drug trafficking charges.

Senator Leila de Lima is accused of receiving money from detained drug lords.

She has insisted on her innocence and says the charges are an attempt to silence her criticism of Mr Duterte's war against drugs.

She had spent the night in the Senate in Manila to evade arrest on Thursday.

But on Friday morning she surrendered to police, telling reporters: "It is my honour to be imprisoned for the things I am fighting for.

"They will not be able to silence me and stop me from fighting for the truth and justice and against the daily killings and repression by the Duterte regime."
