The United Front for Democracy against Dictatorship (UDD) will hold a mass gathering of the red-shirts in front of Laksi temporary prison on Jan 15, UDD co-leader Jatuporn Prompan said on Friday.

Mr Jatuporn said the rally will call on the government to issue an amnesty decree for political prisoners of all colours, including members of the Anti-Thaksin Pitak Siam group.

The UDD co-leader insisted that the amnesty should not cover UDD co-leaders facing charges of terrorism and former premier and Democrat Party leader Abhisit Vejjajiva and ex-deputy prime minister Suthep Thuagsuban facing charges of attempted murder relating to the 2010 protests.

He said the gathering will be from 10am until 3pm.
