In the letter Advani said that it would have been better if she (Sonia) had clarified on the black money issue earlier. Then the BJP task force would not have made the allegations, he wrote in the letter. Advani also regretted any hurt caused to Sonia.
A BJP task force letter written by Advani at the BJP's national executive at Guwahati had alleged that Sonia and her husband Rajiv Gandhi held foreign bank accounts.
In response, Sonia wrote a letter denying that she or any one from her family had any such accounts.
The BJP has been demanding that the names of those with money stashed abroad be made public.
However, Congress sources told CNN-IBN that Advani has not apologised to Sonia.
