Final answer:
The Interim Constitution of Nepal 2063 B.S faced challenges such as political instability, uncertain economic frameworks, and difficulties in reconciling diverse political factions.
Step-by-step explanation:
The weaknesses of the Interim Constitution of Nepal 2063 B.S include a lack of political stability, the absence of long-term economic frameworks due to the transitional nature of the government, and the challenges posed by ongoing civil unrest. Despite the peace accord and the formation of a constitutional assembly, economic conditions have been volatile. The transitional phase under the Interim constitution has been unable to firmly stabilize the nation's governance structures, leading to depressed economic activities and deterring tourism, which is crucial for Nepal's economy. Moreover, there remains significant tension between those loyal to the former royal family and those advocating for a republic, indicating the Interim constitution's limited success in reconciling different factions within the country.
