He accused unnamed "destructive elements" of trying "to constantly hinder and sabotage our development tasks".
 
The newspaper quoted Than She as asking the public to "always remain vigilant against these elements and ward off the dangers posed by them".
 
The government has yet to unveil the final version of its proposed  constitution.
 
The opposition National League for Democracy (NLD) party, headed by Aung San Suu Kyi, said on Saturday it was "surprised" by the announcement.
 
Bar on Suu Kyi?
 
The guidelines produced by the secretive convention that drafted the text appear to bar Aung San Suu Kyi from running for president.

One clause bars anyone married to foreigners from standing -  Aung San Suu Kyi was married to Briton Michael Aris, who died in  1999.
 
Another clause requires the president to have a "military  vision" of state affairs.
 
The charter would also reserve one quarter of all seats in  parliament for serving officers, who would be appointed by the  commander-in-chief.

Nyan Win, spokesman for the NLD, said: "I am surprised that they set a date for an election."

He also said that it was premature to plan for national elections when no one has seen the final version of the proposed constitution.

"We have to see the results of the referendum on the constitution. How can they know if it will be a success? It is still early to talk about an election."

The NLD won Myanmar's last election in 1990, but the ruling military government has never recognised the result.

In Bangkok, Thailand, a spokesman for a group of exiled MPs who fled after that vote, said that the elections would be meaningless unless Suu Kyi was freed and took part.
   
"Without the participation of Suu Kyi, the NLD and ethnic parties the people will not accept this constitution," Zin Linn of the National Coalition Government of the Union of Burma, said.

Instead, the generals insisted on drafting a new constitution and convened a so-called National Convention in 1993, which spent the next 14 years in meetings laying out the guidelines for a new charter.
  
Party boycott
 
In the early stages, the NLD participated in the talks, but it later boycotted the convention in protest at Aung San Suu Kyi's house arrest, which is now entering its 12th year.

The convention finally ended on September 3, 2007, weeks after anti-government demonstrations began in Yangon, the former capital, in protest at an increase in fuel prices in mid-August.
  
By the end of September, the protests had turned into the  largest anti-government demonstrations in nearly 20 years.

The military responded with a deadly crackdown in which security forces  opened fire on crowds, killing at least 31 people, according to the UN.
