Since announcing his decision to join DAP earlier this week, former law minister Zaid Ibrahim said many unflattering things have been mentioned about him.

"BN and their cybertroopers, especially, have said plenty of things that would make you cry.

"I am not about to respond to them again. Today, I wish to address my friends and supporters who have their concerns about my new involvement in party politics. They have genuine concerns which I must deal with," he added in a blog posting.

Addressing concerns as to whether he is a team player, the former Kota Bahru MP pointed out that he would not have lasted more than two decades in Umno if otherwise.

"I also lasted 24 years in the law firm that I built from scratch. I am certainly not a prima donna, as people who know me can attest to.

"I come from a humble background and it is not my style to stride about like a peacock flaunting my feathers," he added.

As for those who describe him as being "power crazy", Zaid noted that his decision to relinquish his ministerial post is a sufficient response to that argument.

"Then there are those who call me a 'wild horse', a label that came about when I was a minister tasked with carrying out law reform. I was described as a bull in a china shop trying to change the world in 30 days.

"The truth is, I only had a small window of opportunity to carry out my responsibilities. I knew that Abdullah Ahmad Badawi was being pushed out as prime minister, so I tried to do as many things as possible before that happened.

"This included pushing for compensation for the judges who had been dismissed in 1988. I was also part of the team that started the framework for the establishment of the Malaysian Anti-Corruption Commission, and that worked on the Judicial Appointments Commission," he added.

Zaid also argued out that he is more experienced in opposition politics and older now.

"I will pace myself. I have a number of good qualities too: I am frank and open with my views, I don't harbour grudges and I do not scheme or manipulate others to gain position and power.

"I don't stab my colleagues in the back. I hope this will assure those who stand by me - I am thankful for your support.

"I look forward to working with opposition leaders. I hope we will be a cohesive and united team so that the aspirations of the rakyat can be realised. I am not promising anything more than that, but I will definitely give my utmost for the cause of reform and change of government," he added.

'Forming Kita, my only mistake'

Meanwhile, in an interview with financial website iMoney, Zaid conceded that forming political outfit Parti Kesejahteraan Insan Tanah Air (Kita) after quiting PKR was a mistake.

"Not a smart one. It is the only mistake I made really. Kita was just too expensive, too difficult to move.

"I was quite naive as I was hoping that some friends - some wealthy friends - would chip in, but it didn't work out," he added.

After Umno, Zaid joined PKR but fell out with the party shortly after the Hulu Selangor by-election, in which the veteran lawyer lost to BN.

After Kita lapsed, Zaid announced he would contest in the Kajang by-election of 2014 as an independent against his former party chief PKR de facto leader Anwar Ibrahim, but dropped out of the race before nomination day.

The former minister said he is considering contesting in the coming general election.

"I will probably contest in this election. I have got offers to contest, but I will decide on that, and if I can win and contribute, why not?" he added.

Zaid also said he entered politics to effect change.

"Well, it was not an easy decision (joining politics), but the country was not moving in the right direction and I have always been critical of the way we were moving for many years now.

"I think there is not enough cohesion, even in the opposition, to articulate the way we should go, so I thought I should step in," he added.
