The padyatra, flagged-off by Mr Shah on October 3 from Kannur, the northern district of the state with a history of clashes between CPI(M) and BJP-RSS workers, was to highlight the 'Left's atrocities' in Kerala under the LDF government.
The sources said Mr Shah would walk with party cadres from Pattom to the Puthrikandam maidan, the venue of the valedictory of the two-week-long yatra.
A host of BJP leaders, Union ministers and BJP chief ministers, including Uttar Pradesh CM Yogi Adityanath, have participated in the yatra at different stages. It's led by BJP state chief Kummanom Rajasekharan.
The BJP has lashed out at the CPI(M) over the political violence in Kerala, alleging that their party cadres were attacked and killed by ruling CPI(M) workers.
It was also alleged that the state has become a fertile ground for 'jihadis'.
The ruling CPI(M) has rejected the charges and said that BJP-RSS activists attacked its workers instead.
The CPI(M) has also alleged that the BJP was attempting to create tension in the state by unleashing violence.
