Colombian President Gustavo Petro has requested the resignation of his government's cabinet members, he said in a post on social media on Sunday.

Colombia's interior minister has resigned as a political crisis shakes the government of President Gustavo Petro, following his decision to appoint a controversial politician as chief of staff.

BOGOTA (Reuters) - Colombia's Environment Minister Susana Muhamad said on Sunday she has informed President Gustavo Petro of her resignation from the post.

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.
