La Paz - A day after winning approval of a socialist constitution in a referendum, Bolivian President Evo Morales on Monday reached out to his conservative opposition to create a "national pact" to implement the new document.

On Sunday, 56.8 per cent of the country's more than 3.8 million voters approved the new constitution, according to election commission results with 50 per cent of the votes counted. Exit polls estimated about 60 per cent of voters had approved the document that is designed to give more rights to the indigenous minority and give the government more control over the economy. It would also allow the president to run for a second five-year term.

The results are nationally binding despite profound regional political differences across Bolivia. In four wealthy pro-autonomy provinces, among Bolivia's nine provinces, that are currently led by the opposition to Morales, a majority voted against the new text.

Regional leaders in opposition provinces Santa Cruz and Tarija on election night had asked for a "national agreement" to keep moving forward, but it was unclear what form such a discussion would take.

Bolivia remains deeply divided, though several recent votes have consistently produced majorities for Morales and his policies, which include a declared intention to reverse centuries of discrimination against the Indio majority.

Bolivia's relatively wealthy upper class of European descent dominate the four opposition-led provinces in the eastern lowlands, which have fertile soils and sit on rich deposits of natural gas. (dpa)
