As many as 200 students at the Solomon Islands National University could be barred from graduating because of members of parliament not honouring their sponsorship commitments.
Under the Constituency Scholarship Fund, each MP receives $US44,000 to sponsor students from their constituency through university.
But the Island Sun newspaper reported that payments from some MPs to the university have been slow coming, or have not arrived at all.
The newspaper claimed that one MP owed the university as much as $US64,000 in unpaid fees.
The university said it had been lenient in allowing the students to continue their studies, but warned that unless their local MPs paid their debts, the students would be held back from graduating.
