A NASA rally at Kapsabet grounds, Nandi County on Sunday was interrupted for hours after rowdy youth stormed the meeting.
Police were forced to intervene to repulse the youths who were dressed in Jubilee regalia, chanting anti-Raila slogans.
NASA principals led by Raila Odinga and Kalonzo Musyoka claimed that the group of youths had been paid by Jubilee to disrupt their rally, adding that the journey to rescue the nation was unstoppable.
The rally however resumed after police restored normalcy, with Nasa leaders hitting out at the Jubilee administration for failing to address the challenges facing farmers in the country.
“Since Jubilee took over, farmers have become poorer. The prices of raw milk have gone too low while tea farmers now get only Sh10 per Kilo as a bonus, this is a big failure of the government," Raila said.
He added, "We decided to start our rallies here because we know the significance of this town, this is the headquarters of the Kalenjin community."
The NASA's brigade included Raila's running mate and Wiper leader Kalonzo Musyoka, Musalia Mudavadi, Moses Wetang'ula and Bomet Governor Isaac Rutto.
Kalonzo promised that the opposition was assured of big support in the Rift Valley, despite the region being Deputy President William Ruto's backyard.
Amani National Congress leader Musalia Mudavadi urged the police to ensure that political campaigns were safe, demanding that leaders propagating violence be arrested.
