LIMA (Reuters) - Peru's Keiko Fujimori, the head of the largest opposition bloc, said on Friday her Popular Force party would back a motion being prepared to impeach socialist President Pedro Castillo.

The basis for the challenge against Castillo, alleging he is morally unfit for office, is tenuous and its chance of success unclear. Fujimori narrowly lost the presidential race against Castillo earlier this year.
