Colombia’s foreign ministry has accused Ecuador’s president of «deliberate interference» in its forthcoming election after he promised a right-wing candidate he would lift tariffs.

Daniel Noboa framed his conversation with Colombian presidential hopeful Abelardo de la Espriella on Friday as one with an administration-in-waiting, saying the two had «reached an agreement» on trade and security.

Colombia heads to the polls on Sunday to elect a new president, in an atmosphere of intense political polarisation.
