"I admit that there are flaws in the present Constitution with incompatible patchwork amendments," Rajapaksa said in his election manifesto released here.
    
"I shall implement a new Constitution to meet people's aspirations within one year," he said.
    
The admission by 69-year-old Rajapaksa is being seen as a response to the increasing support to his main challenger Maithripala Sirisena, 63, who is campaigning for democratic reforms and to reduce presidential powers.

Sirisena has promised a new Constitution allied to the Parliament in place of the "present autocratic executive presidential system."
    
Rajapaksa said: "I shall deal with the executive presidential system, electoral system, rule of law and good governance in the new Constitution."
    
On foreign policy, Rajapaksa pledged expansion of ties with India, Pakistan and the SAARC nations.

"My good governance principals will be based not on neo liberalism but on the Indo-Lanka philosophy heritage based on righteous rule which has been time tested over 5000 years."
    
According to the manifesto, his government would perform a peace broker's role in regional and global conflicts.

The incumbent president has been accused by the opposition of nepotism, corruption, disregard to rule of law and politicising all areas of governance.
    
On law and order breakdown, for which Rajapaksa has come under severe criticism, he has pledged to set up a special crime court aimed at ending the drug menace.
    
At the release of the manifesto, Rajapaksa said: "In 2005, I promised peace for all citizens and I delivered that within four years.
    
"We developed the country as we promised in 2010. The latest part will make the country a developed one."

"At this election, people should decide if they should go back to an era of destabilised society or go forward with strength and stability," Rajapaksa, who has been in power for the last nine years.
    
Rajapaksa released his manifesto after his main rival Sirisena did last week. Backed by a joint opposition and a breakaway faction of the country's Sri Lanka Freedom Party, Sirisena has promised several populist measures, including a 10,000-rupee salary increase to public servants, free Internet wi-fi zones across the country and a host of agricultural subsidies apart from constitutional reforms.

Rajapaksa has called for a snap election two years ahead of the schedule.
