YSR Congress MP S P Y Reddy on Sunday joined the rival Telugu Desam Party (TDP), which is set to form the government in Andhra Pradesh.
Reddy, a three time MP from Nandyal, joined the TDP chief N. Chandrababu Naidu here.
Reddy had quit the Congress and joined the YSRCP late last year after the Congress-led UPA government decided to carve out a Telangana state.
He was re-elected to Lok Sabha from Nandyal constituency in Kurnool district.
