Panama President Juan Carlos Varela smiles as he checks food products during a tour to different supermarkets and popular markets in Panama City July 7, 2014. Panama's new president on Monday visited supermarkets to check that they had implemented food price controls to cut the cost of living, measures which also will hit the pocket of his predecessor, retail magnate Ricardo Martinelli. The controls on 22 basic goods including potatoes, beans, chicken and tuna, fulfill a campaign promise made by center-right President Juan Carlos Varela, who won election in May.
