North Korea is reportedly preparing for the largest military parade in its history, believed to be timed to coincide with the most important political meeting of its leadership in decades.

Tomorrow the North Korean regime will hold its most important meeting in 30 years when the communist Workers' Party conference convenes in Pyongyang.

Some analysts believe Kim Jong-Il will use the forum to declare his youngest son, Jong-un, as his successor.

Quoting communist sources in Pyongyang, South Korea's Yonhap news agency is reporting that the military parade will include short and mid-range missile launchers, artillery and tanks.

The agency says about 10,000 North Korean soldiers have been practicing for the parade for two months.
