He planned a marriage between his second son and one of Russian president Vladimir Putin's daughters, according to a new revelation by former advisor to Gaddafi. The dictator approached a bemused Putin to ask if one of his daughters could wed his second son Saif al-Islam Gaddafi, with the aim of strengthening ties between Libya and Russia, the advisor Mohammed Abd El Motaleb al-Houni said. "Gaddafi talked about it with Putin,proposing his son as a future son-in-law, but the Russian president was taken aback and said his daughter did not know Saif al-Islam,"al-Houni said.It maybe recalled that Gaddafi was ousted and killed in a NATO-back revolt in 2011. Saif al-Islam was sentenced to death by a court in Tripoli in a mass trial of former regime figures. He was caught trying to flee Libya in the aftermath of the 2011 revolution.
