Family members of former prime ministers will not be guarded by the top level Special Protection Group commandos, according to the amendments approved by the Union cabinet to the SPG Act. The move comes a couple of weeks after the SPG cover of Congress president Sonia Gandhi and her children Rahul Gandhi and Priyanka Gandhi Vadra and former Prime Minister Manmohan Singh was revoked. The Home Ministry is all set to introduce the SPG Act (Amendment) Bill in the Lok Sabha next week.
