Prime Minister Abdullah Ahmad Badawi vowed to remain in power despite ex-premier Dr Mahathir Mohamad's criticism that he is endangering the economy.

"I will not run. I am here to stay. I have a long-term plan," Abdullah said in an interview with the Umno-owned Malay-language newspaper, Mingguan Malaysia .

Abdullah, who took over from Mahathir in October 2003, said he needed time to implement development projects, which were part of a national development plan to boost the economy.

With all the policies and strategies in place, it would take more than one term to accomplish the mission, he said.

Abdullah added he would not be distracted by criticisms and insults hurled his way because "I know my focus and my aim".

"I will work to ensure all the projects are implemented," he said.

This is the first time Abdullah has indicated that he would continue to lead the ruling Barisan Nasional coalition, which won a landslide victory during the 2004 election.

The remarks come ahead of the annual gathering next week of Abdullah's Umno, when party members are expected to demand Abdullah do more for the economy.

Never-ending feud

Abdullah and Mahathir are embroiled in a bitter dispute, with Mahathir accusing Abdullah of economic mismanagement, corruption and nepotism - charges the incumbent leader has repeatedly denied.

The feud has shocked and dismayed Umno members, who have also raised fears of party divisions.

Mahathir is likely to be absent from the gathering after suffering a mild heart attack, but Abdullah is expected to come under scrutiny, especially now that his first term is well past the half-way mark.

Abdullah expressed regret rather than worry about the accusations levelled at him.

"I am more regretful than worried. Is this the Mahathir that I once knew? This is a never-ending feud ... He is against me and the government in total," the premier said.

"Let him do what he wants but I will look after Umno and the government as this is my responsibility," he added.

Abdullah faces a test of support within the party at the week-long general assembly, where no restrictions have been placed on topics for debates.

Mahathir, who ruled Umno for more than two decades, still holds influence and his criticisms may be defended by loyal supporters.
