SP leader Amar Singh on Monday claimed that party chief Mulayam Singh Yadav was taken into confidence about the cross-border surgical strikes by the Prime Minister's Office (PMO) before the operation was carried out."Prime Minister ke yahan se phone aaya tha, sabko vishwas me liya tha... Mulayam ji ko phone karke bataya (The PMO had called up, took everyone into confidence and informed Mulayam Singh about the strikes)," the Samajwadi Party (leader) said."Mulayam-ji had assured full support to the government in the matter," Amar Singh added.He said the surgical strikes would not have been possible without support from all quarters.Some Samajwadi Party supporters had also put up hoardings in Uttar Pradesh, congratulating the army and Mulayam Singh Yadav over the surgical strikes, giving credit to the SP chief for apparently advising the government to conduct the strikes.
