[6] In February 2020, a development commonly dubbed the Sheraton Move, saw the fall of the ruling Pakatan Harapan (PH) coalition government and the resignation of Prime Minister Mahathir Mohamad after 22 months in power.

Some sources suggest this began due to Prime Minister Mahathir Mohamad attempting to thwart the process of handing over power to his designated successor Anwar Ibrahim, as was promised ahead of his 2018 general election victory.

[39] Ismail Sabri Yaakob is a senior politician in United Malays National Organisation, part of the Barisan Nasional coalition that had governed Malaysia from its independence until their 2018 election loss.

[9][46] The presidential council of Pakatan Harapan held a late-night meeting to discuss handing over power from Mahathir Mohamad to Anwar Ibrahim, who was coined as the "Prime Minister-in-waiting" as promised in the 2018 election.

[53] Azmin Ali, the deputy president of PKR and the Minister of Economic Affairs, also held a meeting with several lawmakers from the party and twenty others at Sheraton Hotel in Petaling Jaya, amidst rumours that the formation of a new governing coalition was being undertaken.

[58] It was speculated that the leaders were there to brief the Agong about the recent political development; the formation of a new coalition government and to declare their support for a new prime minister, effectively blocking PKR's president Anwar Ibrahim from the position.

[94] In an unrelated press conference on the evening of 27 February, Mahathir revealed that the Agong "[could not] find anyone with a distinct majority" to be elected as the prime minister and that a special session of parliament would be held on 2 March to address the predicament.

[98] In the evening, the palace released a statement saying that the Yang di-Pertuan Agong would call the leaders of political parties who have members in the parliament for an audience, to allow them to nominate their candidates for the position of prime minister to break the impasse.

[116] In the evening, the royal palace released a statement announcing that Muhyiddin, in the Yang di-Pertuan Agong's judgment, is likely to command the confidence of the majority of the MPs and was to be appointed as the 8th Prime Minister of Malaysia.

[118] Shamrahayu Abd Aziz, an academic and an expert on the constitution stated that any statutory declaration signed after the Agong's announcement would not make a difference, and the legal way to challenge Muhyiddin's appointment was through a vote of non-confidence in the Dewan Rakyat.

[119] Minutes before the swearing ceremony of Muhyiddin, Mahathir said in a press conference that the Istana Negara had refused to grant him an audience to prove that Pakatan Harapan commanded the support of the majority of the Dewan Rakyat.

[131] Speaker Mohamad Ariff announced on 7 May that he had received a letter on 1 May from Warisan leader Shafie Apdal seeking to table a motion of confidence in Dr Mahathir to show that he could command a majority in the Dewan Rakyat.

Azhar's appointment took place amidst a shouting match between Pakatan Harapan and Perikatan Nasional MPs, after he was sworn in without a voting session by lawmakers, similar to the removal the incumbent Speaker.

[155] On 13 December 2020, UMNO veteran Tengku Razaleigh Hamzah held a joint press conference with his longtime rival Mahathir Mohamad, where he publicly declared his rejection of the 2021 budget tabled by Muhyiddin.

[161] Machang MP Ahmad Jazlan Yaakub held a press conference to personally and publicly announce his withdrawal of support for the PN government and resignation as Chairman of the Malaysian Palm Oil Board (MPOB).

[162] Mohamed Nazri Abdul Aziz held a press conference on the same day to publicly and personally announce his withdrawal of support, declaring he was no longer aligned with PN as an MP, although his coalition was, further reducing Muhyiddin Yassin's majority to only 109 out of 220 MPs.

In the afternoon on the same day, Julau MP Larry Sng confirmed the rumours and signed statutory declarations (SDs) in support of PN with Choong, handing them to Prime Minister Muhyiddin.

[172][15] The session was chaotic; no debate or vote was held on COVID-19 emergency measures and opposition leader Anwar Ibrahim and former Prime Minister Mahathir accused the government of not fulfilling the Agong's request.

[15][176] On 31 July, hundreds of protesters attempted to gather in Merdeka Square, Kuala Lumpur, calling for the resignation of Prime Minister Muhyiddin Yassin over his and the Malaysian government's handling of the COVID-19 pandemic.

[259] On 24 November, Ahmad Maslan of UMNO stated that the party's supreme council has agreed to follow the wishes of the Yang di-Pertuan Agong for BN to join a unity government which is not led by PN.

[261] The Deputy Works Minister Shahruddin Md Salleh of BERSATU resigned from his ministerial position on 4 June, calling his decision to join the Perikatan Nasional government "incorrect" and adding that he should have considered his constituents who "voted for Pakatan Harapan" in 2018.

[305] It came after he was heavily criticised for his decision not to pursue a case against twelve Indian individuals including two state lawmakers who were accused of having connection with Liberation Tigers of Tamil Eelam (LTTE), which was listed as a terrorist organisation in Malaysia.

[309] The Menteri Besar of Selangor, Amirudin Shari called for a meeting with all Parti Keadilan Rakyat (PKR) members of the legislative assembly (ADUNs) at his official residence on the morning of 24 February 2020.

[336] On 4 March, PKR assemblyman from Pemanis, Chong Fat Full formally announced his exit from his party to become a Perikatan-friendly independent, thus resulting in Perikatan Nasional effectively controlling 29 seats in the state assembly against Harapan's 27.

He said for now, Osman would only be called to answer charges regarding allegations of helping the Independent candidate campaign in the recent Slim State Assembly (DUN) by-election (PRK), and no action has yet been taken.

[355] Najib Lep said PAS's decision to transfer him to another seat seemed to want to kill his political career even after showing excellent service as the party's sole elected representative for the past four years.

The speculation followed the call by Benut assemblyman, Hasni Mohammad for BN to choose young people to lead Johor, even though he was previously appointed as the party's Menteri Besar candidate.

Example included PN Independent MP Norhizam Hassan Baktee shouting "babi" ("pig") repetitively to DAP representative Low Chee Leong in response to the latter's "pengkhianat" ("traitor") remark.

He, however, left the issue to the discretion of the Yang Dipertua Negeri, Mohd Ali Rustam to decide whether the State Legislative Assembly should be dissolved or elect a new Chief Minister from among the PH leaders.

[393] On 12 May, two PKR assemblymen representing Sidam and Lunas left the party citing lack of confidence in Anwar and an alleged purge of grassroots members aligned towards Azmin as their reasons, to become independents friendly towards Perikatan Nasional.
