The Telugu Desam Party would initiate disciplinary action against two of its MPs - DK Adikeshavulu Naidu and M Jagannadham - who had defied the party line and voted in favour of UPA Government during the trust vote in Parliament.
The TDP, which has five MPs in Lok Sabha, received a jolt with two of its members switching loyalities and supporting the Congress-led Government in the confidence motion voting on Tuesday night.
"This is a serious betrayal and breach of trust. We will take it seriously and initiate disciplinary action against the erring members," the party's leader in Parliament K Yerran Naidu today said when contacted.
Adikeshavulu Naidu represents Chittoor, the home district of TDP President N Chandrababu Naidu, while Jagannadham, a Dalit leader from backward Mahaboobnagar district, was elected from Nagarkurnool constituency.
Jagannadham is also the party's deputy floor leader in Lok Sabha.
The defiance by two senior MPs came at a time when TDP, a constituent of UNPA, is playing a key role in forging a third front with the help of BSP and Left parties.
Accusing the ruling Congress of offering bribes to MPs to switch loyalities, Yerran Naidu said his party colleagues had come under severe pressure from a UPA lead player.
