Perikatan Nasional chairperson Muhyiddin Yassin today lambasted veteran Umno leader Shahrir Samad, saying that the former Johor Bahru MP is a "foolish" person for challenging Bersatu to withdraw its support for the Umno-led Johor state government.

Speaking at a press conference in Malacca, Muhyiddin said Shahrir was being irresponsible for making such a challenge which can cause another snap polls when the country is still struggling with the Covid-19 pandemic.
