Jakarta – Some 42,300 troops and 11,000 civilian auxiliaries will be deployed to guard the first session of Indonesia's new national assembly in October, reports said Thursday.

The new People's Consultative Assembly (MPR), the country's highest lawmaking body, reconstituted by the June 7 elections, will meet on October 1 and then elect a president in November.

"Security personel will comprise 150 companies from the police and 273 from the military," deputy chief of Jakarta police, Brigadier General Sutanto, said according to the state Antara news agency. Sutanto said a total of 118 companies of civilian auxiliaries will also be readied in the capital to support the troops.

Security authorities including armed forces chief General Wiranto have voiced concern demonstrators will return to Jakarta's streets in the run-up to the selection of a new president.

Although the Indonesian Democracy Party-Struggle, headed by Megawati Sukarnoputri, came first in the elections with 33.7 percent of the vote, her ascension to the presidency is not assured.

The 700-seat MPR, which contains 200 appointees as well as elected parliamentarians is not bound by the polls results.

Megawati's main rival for the top post is incumbent President B.J. Habibie, whose Golkar party came second in the June elections.
