Hundreds of students are expected to march through Dublin city centre today to highlight their ongoing opposition to the Government's plan to re-introduce college fees.
Members of the USI camped outside Leinster House overnight as part of the protest and are organising a rally for this afternoon.
The protest is timed to coincide with the deadline for cabinet ministers to submit their views on a range of fees options presented earlier this year by Education Minister Batt O'Keeffe.
Mr O'Keeffe will examine the views of his colleagues before presenting a plan to the Dáil next month.
The minister has already indicated that he favours a student-loan system whereby graduates would repay their fees once they have entered the workforce.
