Lucknow, Nov 17 (IANS) Bharatiya Janata Party (BJP) rebel and Bharatiya Janshakti Party founder Uma Bharti Tuesday said she is willing to join the National Democratic Alliance (NDA) but not the BJP.

'I have written a letter to NDA convenor Sharad Yadav and L.K. Advani in this regard. The past five years (since I left BJP) were a bitter experience as it is very difficult carry on politics at national level single handedly,' Bharti said in a press conference here.

'If we keep going alone, we will be confined to only one or two states,' she added.

Bharti, who also met BJP rebel Kalyan Singh, welcomed his decision to part ways with the Samajwadi Party (SP).

Samajwadi Party chief Mulayam Singh Yadav abruptly dumped Kalyan Singh last Saturday after his party's dismal showing in the recent assembly by-polls in Uttar Pradesh. Kalyan Singh did not hesitate to display his intent to secure re-entry into his parent party, and the next day he expressed regret at associating himself with Mulayam Singh.

'It was only the Ram Mandir issue that got Kalyan Singh the chief minister's chair and I support him over the issue. Even Lord Ram will forgive him for parting away from Mulayam Singh and taking the pledge for the construction of the Ram Mandir in Ayodhya,' Bharti said.

After the meeting, Kalyan Singh once again said that he will make all possible efforts for the construction of the Ram temple.

'It (Ram Mandir) will be constructed one day and I will give all possible support to the BJP for this cause,' Singh told media persons after meeting Bharti. Bharti also said she will also extend all possible support to Kalyan Singh for the 'noble cause'.
