Basuki Tjahaja Purnama

Basuki Tjahaja Purnama, popularly known by his Chinese name Ahok, is accused of insulting the Koran.

Mr Purnama has apologised for the offending remarks but denies committing blasphemy, which carries a maximum five year jail sentence.

The case is being seen as a test of religious tolerance in Indonesia.

Mr Purnama is the city's first non-Muslim governor in 50 years and there are some who fear the trial signals the growing influence of hardliners in the world's largest Muslim majority nation.

Popularly known as "Ahok", he is accused of insulting the Koran while campaigning in governorship elections.

Mr Purnama is a Christian from the Chinese ethnic minority and the first non-Muslim to lead the city.

The case has prompted fears of a rise in tensions in the largely Muslim country.

The naming of Mr Purnama as a suspect means prosecutors can bring him to trial. If found guilty he faces up to five years in prison.
