ABUJA (Reuters) – Nigeria’s Senate dealt an unexpected blow to President Muhammadu Buhari on Tuesday by rejecting his plan to borrow $30 billion abroad for infrastructure projects and budget support until 2018.

Senators threw out the plan, introduced last week, without debate. When a surprised Senate President Bukola Saraki held a second vote, most senators shouted again “Nay”.

Buhari’s borrowing plans had included the sale of Eurobonds worth $4.5 billion and planned budget support of $3.5 billion.

The shock vote undermines the president’s authority as he tries to lift the OPEC country out of its first recession in more than 20 years, triggered by low global oil prices. Crude oil sales account for about two-thirds of government revenue.

Some lawmakers, including from Buhari’s ruling All Progressives Congress (APC), have objected to government plans to sell oil and other assets to raise badly needed hard currency.

Buhari had already sent a draft budget for 2017 to parliament for approval, detailing plans to spend a record 6.866 trillion naira ($22.55 billion).

The planned spending is up from this year’s 6.06 trillion naira budget and seeks to stimulate growth by funding infrastructure development to increase manufacturing, create jobs and reduce costly imports.

The government has held talks for months with the World Bank, China and other institutions to fund a 2016 budget deficit of 2.2 trillion naira but so far only the African Development Bank has publicly confirmed a planned loan of $1 billion.

Nigeria also wants to sell $1 billion in Eurobonds by the end of the year.
