Observers told Climate Home that Susana Muhamad's resignation while she holds Colombia's COP16 presidency could affect UN nature talks

The demand came after Petro on Tuesday subjected his Cabinet to a five-hour public dressing down on state TV, accusing several officials, including his trade, education and health ministers, of falling behind on the delivery of key projects.
