On 2 June 2020, only three months after PN swept into power in March, he expressed his readiness to resign as the Deputy Minister of Works to "save" his party, BERSATU which was split into two factions led by former party chairman and former Prime Minister Mahathir Mohamad as well as party President and Prime Minister Muhyiddin respectively who were embroiled in a political tussle. Two days later on 4 June 2020, he officially resigned from his position as the Deputy Minister of Works. However, a picture of a letter sent to Muhyiddin stating that he would remain a supporter of the government as a backbench MP was leaked online. Despite this, he later met with Mahathir who is allied with the opposition coalition PH. It was unclear whether Shahruddin supports the PN or PH coalition, with Shahruddin stating that he would address the matter via social media in the future.[4] On 19 July 2020, his BERSATU membership was terminated after he had issued a notice to change the position of his seat in the Dewan Rakyat from the government bloc to the opposition bloc.[5]
