Senator Shehu Sani has explained why he revealed how much he and his colleagues receive monthly as running cost.
Sani, who represents Kaduna Central Senatorial District in the National Assembly, had confirmed that each Senator gets N13.5 million as running cost.
The lawmaker noted that this was in addition to the over N750,000 monthly consolidated salary and allowances of each member of the Senate.
He, however, kicked against allowances, advocating that Senators should only be paid salaries.
In an interview with BBC, Sani said "I decided to burst it open. It was a moral issue.
"The National Assembly is one of the most non-transparent organs of government. It pricked my conscience and I decided to burst the bubble and open the National Assembly to public scrutiny."
"If the expenses payment system was ended then parliament would only be attractive to people who contribute ideas," he said.
