Patna: Prime Minister Narendra Modi arrived here on Tuesday to attend the concluding ceremony of the Champaran Satyagraha's centenary celebrations in Motihari.

Modi was received by Bihar Governor Satyapal Malik, Chief Minister Nitish Kumar, Union Minister Ram Vilas Paswan and several senior BJP leaders.

According to police officials, Modi reached Patna in an Indian Air Force aircraft and will go to Motihari by a helicopter.

The Prime Minister is slated to address 20,000 'Swachhagrahis' (cleanliness ambassadors).

He will also lay the foundation stone for four sewerage projects.

The theme of the centenary celebrations is "Satyagrah se Swachhagrah".

Mahatma Gandhi launched the Champaran Satyagrah on April 10, 1917, against the British to fight for rights of farmers who were forced to undertake indigo cultivation.

Swachhagrahis are the 'foot soldiers' and motivators to implement the Community Approaches to Sanitation at the village level.
