The US military is in constant conflict with Houthi armed forces. Why is the Yemeni government changing prime ministers at this time?

On May 3rd local time, Ali Mi, chairman of the Presidential Leadership Council of Yemen, appointed Salim Saleh bin Brik as the new prime minister of Yemen. Brik served as the Minister of Finance of Yemen in 2018 and previously held positions in the Yemeni government's finance and customs departments. Niu Xinchun, professor at the Institute of China-Arab Studies at Ningxia University, stated that the main reason for the change in prime minister in Yemen is internal power struggles. The conflict between the former prime minister and the chairman of the Presidential Leadership Council in Yemen was too great, as these two individuals held the most power in the Yemeni government, eventually leading to the prime minister resigning and the chairman of the Presidential Leadership Council appointing a new prime minister. This also reflects the current fragile political situation in Yemen.
