President Pedro Pablo Kuczynski offered himself as a mediator, inviting the teachers' delegates to meet with him in the Government Palace to reach a solution; only the leaders of the CEN were received, along with the leaders of Cuzco, but not the representatives of the bases led by Castillo.[24][25] Due to this, the strike worsened, with the arrival of the teachers from all regions to Lima, holding marches and rallies in the capital.[26] Keiko Fujimori and her Fujimorist supporters – opponents of the Kuczynski administration – assisted Castillo with the strike in an effort to destabilize the president's government.[14]
