Deputy Prime Minister Ahmad Zahid Hamidi today expressed unhappiness over the Swiss authorities’ deicison to make public its request for Malaysian cooperation in its 1MDB probe.

Zahid said the request should have been relayed through official channels.

"Making a public statement, in my opinion, is not a proper move.

"Not only it could strain ties between two countries but also lead to bias in media reports," Zahid told reporters after delivering his closing address at the Tourism Fair 2016 in Kuala Lumpur.
