Today the Royal Gazette published the announcement of the upgrade of TAO Kut Nok Plao to a subdistrict municipality (thesaban tambon) (เทศบาลตำบลกุดนกเปล้า). The new municipality is located in Mueang Saraburi district, Sara Buri province. The announcement was made in Volume 125, issue พิเศษ 21 ง, page 22, published on January 30 2008. It was signed and approved on July 12 2007 already, and took effect on July 19 2007.
The article on the Mueang district in the Thai Wikipedia already contained this new municipality, but also Takut (ตะกุด), which seems to be pending the announcement as well. I guess thesaban announcements will become a regular topic for the next time, the previous one was just one week ago, and if I am not mistaken there are quite a lot municipalities pending announcement.
