Pakatan Harapan is unfazed by the political bloc being formed by PAS and a multiracial opposition party, according to PKR deputy president Mohamed Azmin Ali.

He said he did not feel it was a challenge to Pakatan Harapan with the formation of the bloc, which will be established on Wednesday.

"No lah, this is just a strategy. In politics, we must have strategy," he said when asked if Harapan felt the new bloc would represent a serious challenge to his coalition.
