South Korea's Prime Minister Chung Un Chan offered his resignation Thursday over the government's failure to get parliamentary approval to revise the planned relocation of ministries to a newly planned administrative town.

Chung, 64, a strong supporter of President Lee Myung Bak, was named premier in September.

Lee's government wanted to scrap the previous administration's plan to relocate half the ministries to Sejong, a town under construction south of Seoul.

The president is expected to accept Chung's resignation.
