Sri Lanka's sports minister and the president's nephew, Namal Rajapaksa, has resigned from his position amid growing public outrage over the country's economic crisis and shortages of food, fuel and medicine.

The entire Sri Lankan cabinet has also handed over letters to Prime Minister Mahinda Rajapaksa offering to resign from their positions due to the country's economic crisis, Education Minister Dinesh Gunawardena told reporters late Sunday.

Gunawardena said the prime minister and President Gotabaya Rajapaksa will take appropriate action on the cabinet's offer to resign.

Government coalition parties are demanding that a caretaker cabinet be appointed to pull the country out of the crisis.
