Colombian President Juan Manuel Santos has appointed a team of senior government officials to launch talks with the opposition on changes to a peace deal with the Farc rebel group. Mr Santos made the announcement after meeting with political party leaders.The peace deal was rejected by a narrow margin in a referendum on Sunday.<br/><br/>Former President Alvaro Uribe, who led the "no" campaign, did not attend the meeting but appointed three negotiators to hold talks with the government. Mr Uribe, a senator and leader of the Democratic Centre party, wants rebels who committed serious crimes to serve prison sentences and for some of the Farc leaders to be banned from politics. <br/><br/>The peace deal was signed last week after nearly four years of negotiations, which were held in the Cuban capital, Havana.
