News of the affair between senior Congress leader Digvijaya Singh and television anchor Amrita Rai has been the talking point in a highly-charged election environment. Now, a third voice has emerged in righteous indignation over the relationship, this time from within the family.Rubina Sharma Singh, who is married to Digvijaya’s younger brother Lakshman, says she finds it “ironical” that he is involved with a woman who is nearly 30 years younger, not to mention that his own children are older than the partner he has chosen.The ‘irony’ digs up an old wound for Rubina. In an exclusive interaction with ETPanache, she alleges that Digvijaya “created a lot of tension” over her marriage to Lakshman 13 years ago. First, because she is not a Rajput and second, because there is a 13-year age gap between the couple. “It was very painful and he (Digvijaya) made my life very difficult,” says Rubina, adding that he tried to create “a lot of unnecessary tension” between her and Lakshman’s two children from his first wife, who died long before they got married. Rubina, who is designer Rohit Bal’s niece, now lives in Bhopal where she works with cancer patients. Lakhshman Singh, originally a Congressman, had shifted to the BJP for a few years before returning to the Congress last year.Rubina claims Digvijaya’s affair began while his wife was still battling cancer. “I am not against his relationship and I have no business to comment on it. But I find it very ironical that he is doing exactly what he was against 13 years ago,” she says.What is more difficult for Rubina to digest is that Digvijaya has not apologised “for being so nasty” to her all these years. And on the way Singh’s relationship has been panned on social media, Rubina is unsparing. “No public figure should expect that their private life will not be talked about. You can’t pick and choose what people should know about you,” she says.On her own relationship with Lakshman, Rubina says she got introduced to him through his wife Jagriti, and got to know him better after Jagriti died. “I share a beautiful, loving relationship with Lakshman’s children,” she says. Lakshman Singh refused to comment on the issue while Digvijaya could not be reached despite repeated attempts.
