President Muhammadu Buhari on Tuesday requested the House of Representatives to approve another tranche of $200million World Bank loan for Lagos State.
The WB had, in 2010, offered a Development Police Operation facility worth $600m to the state to be operated in three tranches of $200m per annum.

The President’s request was conveyed in a letter the Speaker, Mr. Yakubu Dogara, read to members on the floor, soon after they resumed from a six-week annual break on Tuesday.

The letter explained that the request was for the DPO II.
Part of the letter reads, “I seek your support to facilitate the consideration and early approval of the DPO II loan of the US$200m to enable the state to consolidate on the gains of the second tranche of the operation (DPO) II.”
In August, Buhari sent a similar request to the National Assembly in respect of Edo State.

In the case of Edo State, he requested approval for $75m in the second tranche of the total of $225m facility the bank offered Edo State.
The President, in a separate letter read to members on Tuesday, also sought the approval of the legislature to raise Nigeria’s proposed Diaspora Bond to $300m.
However, Buhari explained that the raise was needed to accommodate the “huge amount of capital” required to bridge the infrastructure gap in the country.

He also informed the House that Nigerians in the Diaspora had shown interest in the bond.
Buhari stated, “The purpose of this letter, therefore, is to request approval of the House of Representatives to increase the amount proposed to be raised through the Diaspora Bond from US$100m to a maximum of US$300m.”

Economic waste

A state loan that was already requested and approved long before PMB became president.

The only reason why PMB is sending a request letter to the NA is because it is a foreign loan and so requires Sovereign backing. Also, it may have been included in the loan offer letter that one of the "conditions precedent to drawdown" is that the president must make the request on behalf of the state.
