Minister in the Prime Minister's Department Abdul Rahman Dahlan has threatened to sue PKR vice-president Rafizi Ramli for alleging his brother received a contract to organise the "Expo Negaraku".

Rahman, who oversaw the organising of Expo Negaraku, said it was a case of mistaken identity by Rafizi.

"I was just informed that Rafizi today held a press conference to accuse me of appointing my brother as the contractor of Expo Negaraku.

"Rafizi messed up big time, Raslan Dahlan is not my brother. Rafizi has ill intent," he said in a series of tweets.

Earlier today, Rafizi published a press statement on his blog titled: "The organising of Expo Negaraku is managed by a company owned by Rahman Dahlan's brother."

One of the shareholders of Pico Integrated Exhibits Sdn Bhd, which manages the expo, is listed as Raslan Dahlan.

Rafizi's statement has since been removed...
