Former prime minister Dr Mahathir Mohamad today alleged that his successor Muhyiddin Yassin was "afraid" of losing the support of six MPs and was now seeking "replacements".

"He is finding replacements. Where from? Perhaps PKR. But the cost is high," wrote Mahathir on his blog "chedet.cc" today.

So far, Muhyiddin has managed to pass legislation in Parliament with the support of 111 MPs at most, while the opposition mustered no better than 109 in opposing.
