Many, particularly the MUDA Youth Party, argued that a state of emergency or the brink of collapse was not necessary. If Muhyiddin`s main need is to adopt only the budget, the confidence and supply agreement can be introduced, as proposed by MP Muar Syed Saddiq Syed Abdul Rahman. In a parliamentary democracy based on the Westminster system, trust and supply are necessary for a minority government to retain power in the House of Commons. “It comes from those old head of state relationships, where you have to make sure there is a majority democratic principle – that representatives express confidence or confidence in those elected to govern,” Woodman said. This concerns the approval of support for the votes of no confidence. It is not an allusion to the trust, or in any other way, that the signatories of the agreement have intertwined. In New Zealand, trust and supply agreements are common because of the MMP system used in the country. Parties that offer confidence and supply play a more important role than in other countries, with members of support parties often appointed to ministerial portfolios outside the cabinet.  New Zealand codified in its ministerial manual the procedures it has put in place to train these governments.
 Remotely, the two agreements may seem so similar that many use the word “coalition” to refer to trust and supply agreements. The terms “trust” and “supply” refer to the two most important constitutional requirements of a government. The DUP says it is ready to support the government in the votes in the British Parliament, in accordance with this agreement. Following the 2017 provincial election in British Columbia, the B.C. Green Party agreed to a confidence and supply agreement in support of the Democratic Party of British Columbia.  The acting B.C. Liberal Party briefly attempted to form a government, but was immediately defeated by the NDP and the Greens in a vote of confidence.  The political calculation that Varadkar`s splendour would come was correct. Perhaps less expected was that the confidence and offer of their opponents, notably Sinn Féin, would be used against Fianna Féil. After the 2017 general election, in which Theresa May`s Conservative Party had no majority, a confidence and supply deal was reached with the Democratic Unionist Party.
 Between 1977 and 1978, Jim Callaghan`s Labour Party remained in power through a confidence and supply agreement with the Liberal Party, in an agreement known as the lib-lab pact. In exchange, Labour accepted modest political concessions for the Liberal Party.   The first condition is that Parliament have confidence in the government.
