NEW DELHI (AFP) - The ruling party of India's Prime Minister Narendra Modi announced on Wednesday (April 17) that it will field a candidate accused of involvement in a deadly 2008 bomb blast in the country's ongoing national election.

Pragya Singh Thakur, a 48-year-old female Hindu monk, is out on bail while she faces charges related to the attack that killed six people.

She announced on Wednesday that she will run for a seat in the city of Bhopal on the ticket of Mr Modi's Bharatiya Janata Party (BJP).

Thakur, a firebrand speaker, made national headlines after the blast close to a mosque in western Maharashtra state's Malegaon city that also injured around 100 people.

She was arrested shortly after the attack and was described by the authorities as a leading plotter.

Indian law allows candidates facing court cases to run up until the time of any conviction.

"All conspiracies against me have failed. I am an ascetic monk and will ensure justice and respect for my country," Thakur said, clad in traditional Hindu saffron clothes, at a press conference in Bhopal.

"I am confident, fully confident. I am ready for politics and (this) religious war," she added, flanked by regional party leaders.

Thakur was released on bail in 2017 and has had one charge against her dropped, but still faces other charges in the ongoing trial.

Her candidacy in Bhopal - a BJP stronghold constituency in a key heartland state - is expected to polarise local voters.

Her main rival is the outspoken and controversial Digvijaya Singh, from the opposition Congress party.

Hindu nationalists accuse Mr Singh of using the term "saffron terror", which they view as objectionable, to refer to acts of violence by right-wing extremists targeting areas with large Muslim populations.

India's election is taking place in seven phases, with voting in Bhopal not scheduled until May 12.

Results in the vote, the world's largest, are expected on May 23.

The election is seen as a referendum on Mr Modi, who is seeking a second term from the country's 900 million voters.

The opposition Congress party has tried to undermine support for Mr Modi by pointing to his lacklustre economic performance in the last five years.

The BJP, meanwhile, has focused on Mr Modi's key social schemes and a hardline nationalist stance.
