(Reuters) – Colombia’s government and Marxist FARC guerrillas scrambled on Monday to revive a plan to end their 52-year war after voters rejected the hard-negotiated deal as too lenient on the rebels in a shock referendum result that plunged the nation into uncertainty. Any renegotiated peace accord now seems to depend on whether the Revolutionary Armed Forces of Colombia (FARC) could accept some tougher sanctions against them. “No” voters, who narrowly won Sunday’s vote, want assurances the rebels will hand in cash earned from drug smuggling, spend time in jail, and earn their political future at the ballot box rather than get guaranteed unelected seats in Congress.
