President Recep Tayyip Erdogan on Saturday accused Turkeys main opposition party of siding with terrorism, as a three-week "march for justice" led by its chief neared its ending point of Istanbul.
Some analysts have seen the 450-kilometre (280 miles) trek from Ankara to Istanbul led by Republican People's Party (CHP) leader Kemal Kilicdaroglu as a significant challenge to Erdogan but the Turkish strongman has regarded it with disdain.
