Diplomats warned Friday of a looming showdown in negotiations to reach the world's first deal to curb plastic pollution, after a new draft text emerged littered with competing visions and ongoing disagreements. Panama's Monterrey said that if nations opposed to cutting production are "not willing to lead, please leave it to the rest of us and get out of the way". "Mopping the floor when the tap is open is useless," said the EU's Anthony Agotha. Nearly 200 nations are in South Korea's Busan with the goal of sealing a landmark deal by Sunday, capping two years of negotiations. IMAGES AND SOUNDBITES
