Tun Dr Mahathir Mohamad said he had never transferred any donation to be used for the elections into his personal account.

Describing the allegations as “baseless” and “slander”, Dr Mahathir said, he was also willing to have his bank details during his 22 year tenure as prime minister be inspected by those with no personal interest to confirm this.

“During the 1964 and 1969 elections, I had received RM20,000 from the Head Office to be distributed to Parliamentary and State constituencies.

“As I was not willing to hold this large sum in cash, I had banked in the money into my account and issued a cheque to the Election Committee of Parliament and State Assembly for distribution as determined by the Head Office.

“This money is not from donors but UMNO’s money that is usually handed out to constituencies for use by candidates,” the former prime minister wrote in his latest blog entry.

He said, when he was expelled from the party in 1970, his home and clinic had been searched by the Internal Revenue Board.

“They found the cheque stubs that I had issued and they claimed that I did not declare my income in full.

“They had fined me some RM300,000 with a warning that if I disagreed and brought the matter to court, I would be fined three fold.

“I did not go to court. Instead I appealed that the money which was deposited into my account was from the party. But the UMNO Headquarters refused to admit the money was from the party,” he said.

He said, he was finally fined RM130,000 and at that time we was already appointed a Minister in the government.

“I paid the fine in installments and only finished paying it when I became the Deputy Prime Minister,” he said.
