Ajit Singh-led Rashtriya Lok Dal (RLD) on Monday joined the NDA fold and announced that the 'formidable alliance' would work towards a change in government in the Centre and in Uttar Pradesh.

"With this addition, we are sure to bring an end to the suffering of the common man under the five-year-long UPA rule. It is also a step towards ending the SP and BSP misrule of Uttar Pradesh," senior BJP leader LK Advani said here on Monday.
