The former Bihar Chief Minister will now be given 'Z' category security and be guarded by an armed commando squad of the Central Reserve Police Force, in accordance with the protocol of the scaled down cover, the sources said.
Mr Yadav will not have National Security Guard black cat commandos guarding him any more. The NSG only provides 'Z+' security cover.
The decision was taken after the Union home ministry recently reviewed the threat levels of various VIP protectees, the sources said.
The 'Z' cover of Union minister Haribhai P Chaudhary has also been scaled down to 'Y+', entailing less manpower and other paraphernalia, they said.
The minister of state for coal and mines was accorded the larger security cover of central security forces commandos when he was minister of state for home.
