Advantages and Disadvantages of a one-party system

Advantages of a one-party system:

All MPs would have the same rights. All MPs would have more right under this system. If our political representatives do not have a right to free expression and the ability to dissent from the leadership, the people are not being properly represented. Such a party can countenance any view and people holding a particular view, however unpopular, can still hold it even if they are in a minority and cannot have their way. It will enable MPs to vote according to their consciences, because under such a system, all votes would be free votes. In this constitution will be the condition that no member or group of members can deprive another member of his position and membership without a proper hearing, allowing the member proper legal representation and a publicized appeal. There would no longer be any problems about party funding.

Disadvantages of a one-party system:

Not all voices are heard or represented in a one party system. It is a totalitarian government or a right-wing totalitarian. Freedom can be restricted or limited. This form of government may lead to communism. You have less choice, less selection, less variety, less ideas (generally speaking), more control over people. Most political parties are organized from the top down, so they tend to reinforce the power of those who already have power at the expense of those they don't. A one-party system does not easily allow for dissent from outside the party, and the structure of the party is such that it does not allow for dissent either. So, a one-party system is basically undemocratic, although it may be efficient as a ruling party.

Substantiate:

The Communist Party of China (CPC) is the founding and ruling political party of the People's Republic of China (China). The CPC is the sole governing party of China, although it coexists alongside 8 other legal parties that make up the United Front. It was founded in 1921, chiefly by Chen Duxiu and Li Dazhao. The party grew quickly, and by 1949 the CPC had defeated Kuomintang in a 10-year civil war, thus leading to the establishment of the People's Republic. With a membership of 82.6 million, it is the largest political party in the world.

The CPC is organized on the basis of democratic centralism, a principle conceived byRussian Marxist theoretician Vladimir Lenin which entails democratic and open discussion on policy on the condition of unity in upholding the agreed upon policies. The highest body of the CPC is the National Congress, convened every fifth year. When the National Congress is not in session, the Central Committee is the highest body, but since the body meets normally only once a year, most duties and responsibilities are vested in the Politburoand its Standing Committee. The party's leader holds the offices of General Secretary(responsible for civilian party duties), Chairman of the Central Military Commission(responsible for military affairs) and state president (a largely ceremonial position). Through these posts the party leader is the country's paramount leader. The current party leader isXi Jinping, elected at the 18th National Congress (held in 2012).

While the CPC is still committed to communist thought, mainstream foreign opinion believes the party to be non-ideological. According to the party constitution the CPC adheres toMarxism–Leninism, Mao Zedong Thought, socialism with Chinese characteristics, Deng Xiaoping Theory, Three Represents and the Scientific Outlook on Development. The official explanation for China's economic reforms is that the country is in the primary stage of socialism, a developmental stage similar to the capitalist mode of production. The planned economy established under Mao Zedong was replaced by the socialist market economy, the current economic system, on the basis that "Practice is the Sole Criterion for the Truth" (i.e. the planned economy was deemed inefficient).

Since the collapse of Eastern European communist regimes in 1989 and the dissolution of the Soviet Union in 1991, the CPC has emphasized its party-to-party relations with the ruling parties of the remaining socialist states. While the CPC still maintains party-to-party relations with non-ruling communist parties around the world, it has since the 1980s established relations with several non-communist parties, most notably with ruling parties of one-party states (whatever their ideology), dominant parties in democratic systems (whatever their ideology), and social democratic parties.

Currently, Singapore is a multi-party system.

Singaporean politics have been dominated by the People's Action Party (PAP) since the 1959 general election when Lee Kuan Yew became Singapore's first prime minister (Singapore was then a self-governing state within the British Empire). The PAP has been in government and won every General Election since then. Singapore left the Commonwealth in 1963 to join the Federation of Malaysia, but was expelled from the Federation in 1965 after Lee Kuan Yew disagreed with the federal government in Kuala Lumpur. Foreign political analysts and several opposition parties including the Workers' Party of Singapore and the Singapore Democratic Party (SDP) have argued that Singapore is a de facto one-party state. 

However, there are some people who think that Singapore is good as a one-party state as they think that a two-party or multi-party system forces each party to serve party interests, sometimes at the expense of the country's progress, but a one party system help steer the country in one direction. They say "Bigger nations with a two-party or multi-party system can afford to falter and recover. For a small country like Singapore, there is no room for second chances."
