The aide to prime minister's wife Rosmah Mansor has fired salvoes at PKR secretary-gneral Rafizi Ramli for revealing her boss' use of a private jet.

Rizal Mansor said the revelation was intended to create a negative perception against Rosmah amid the Kuala Kangsar and Sungai Besar by-elections.

"He should be using the campaign period to tell the rakyat what his party has contributed to the rakyat and not raise questions that are unrelated to the by-elections.

"At least, Rosmah inspired a programme that has benefited thousands of children and this programme even received international recognition.

"What kind of programme has YB (Rafizi) done?" he said in a statement to Malaysiakini.

Rizal was referring to the early childhood programme, Permata, which was the brainchild of Rosmah.
