Payment of overhead allowances to lawmakers inaugurated on Tuesday in the first three months will increase their total allowances to N19.89bn.
469 lawmakers would get N4.68bn as welcome package to sort out accommodation and furniture issues.
Each senator will receive N40.5m for three months as overhead allowance, with each member of the House of Representatives receiving N30m for the same purpose.
This means that 109 senators will get N4.41bn as overhead allowance for the first three months while the 360 Reps will get N10.8bn in their first three months.
Added to the N4.68bn for accommodation and furniture, the legislators will get N19.89bn within their first three months in the red and green chambers.
