However, Natwar Singh did not join the BJP. Instead, in mid-2008, both Singh and his son Jagat joined Mayawati's Bahujan Samaj Party, only to be expelled by that party within four months (in November 2008) for alleged indiscipline, anti-party activities and "lack of faith" in the ideology of the Bahujan Samaj Movement. In fact, Singh had been demanding a Rajya Sabha seat (which had apparently been promised before he joined the party) and Mayawati had changed her mind on that matter. After this episode, Natwar Singh, having suffered several personal tragedies in a short period, retired from public life.
