Rajya Sabha MP Amar Singh, who was expelled from SP in 2010, will share the dais with party supremo Mulayam Singh Yadav at a function here.
Singh was quoted by a news agency as saying that Mulayam Singh Yadav personally called him to attend inauguration of Janeshwar Mishra park in Lucknow.
However, the MP ruled out any possibility of joining the party again.
Singh, a former national general secretary of SP, had contested Lok Sabha polls on Rashtriya Lok Dal (RLD) ticket from Fatehpur Sikri seat of UP but lost. His Rajya Sabha tenure is also going to end later this year.
The party had expelled him and actor-turned-politician Jaya Prada on February 02, 2010 for indiscipline and indulging into anti-party activities that the party claimed dented its socialist image.
