NICOSIA, Cyprus--Cypriot lawmakers are expected to narrowly approve the island's 10 billion euro bailout deal in a parliamentary vote expected later Tuesday, paving the way for the country to receive its first installment of aid next month.

The deal, which will likely squeak through with only a thin one to two seat majority in Cyprus's 56 member legislature, caps a month and-a-half long financial crisis that rocked the island and threatened to send the country hurtling out of the euro zone.

Under the terms of the agreement, reached earlier this month, Cyprus has agreed to take some EUR13 billion ($17 billion) worth of measures to cut its deficit and restructure its banking system, in exchange for the loan from its euro-zone peers and the International Monetary Fund.

Among the austerity measures, Cyprus has agreed on a range of public spending cuts on everything from government travel expenses to pension benefits, as well as higher taxes on companies and consumers. At the same time, the government has moved to shut down the island's second biggest bank, Cyprus Popular Bank PCL (CPB.CP), and radically overhaul its largest, Bank of Cyprus PCL (BOCY.CP), something that will lead to steep losses for large, uninsured deposit holders.

The austerity measures, the overhauls in the financial sector, and the imposition of recent capital controls--the first imposed by a euro-zone country--are expected to push Cyprus deep into recession this year, with the economy officially forecast to shrink by 8.7% in 2013. Many private economists say the downturn could be much deeper.

In remarks to journalists hours ahead of the vote, Cyprus President Nikos Anastasiades called on Parliament to give broad support for the deal. "An appeal: our country is passing through a critical time that calls for a sense of national responsibility and conduct in a manner which is consistent with the greater good."

Cyprus's main opposition party, Communist AKEL, and its junior ally, the Socialist EDEK party, say they will vote against the agreement. AKEL has also called for a referendum on whether the country should even remain in the euro-zone.

But supported by two parties--Democratic Rally and the Democratic Party--who back the government, and with the support of one lawmaker from the pro-government European Party, the loan deal is expected to win 29 votes in favor--versus 27 against.

Earlier Tuesday, Cyprus's Parliament began an all day debate on the deal, pausing in mid-session to pass a handful of secondary bills--relating to public sector wage and pension cuts and a new property tax, among other things--implementing the agreement.

The vote on the bailout itself is expected at around 1900 GMT, and follows ratification earlier this month by the German and Dutch parliaments as well. Other euro-zone members are likewise expected to approve the loan in coming weeks, while the IMF executive board is expected to give the greenlight to its EUR1 billion portion of the bailout in late May.
