Question

Why did corruption increase when opposition political parties were banned in Ghana?

Nkrumah’s government held too much power, and officials could do whatever they wanted.
Opposition parties operated secretly and illegally, and they tried to undermine the government.
Citizens revolted against Nkrumah’s rule, and crime became common among workers.
Opposition parties ran on anti-corruption platforms, but they won no support from the public

Answer 1

"Nkrumah’s government held too much power, and officials could do whatever they wanted."

When opposition parties are banned the normal checks on government — parliamentary scrutiny, independent media, and political competition — disappear. That concentration of power creates impunity, patronage networks, and fewer incentives for honesty, so officials can misuse public resources with little risk of accountability.
