Reports from Solomon Islands say the government plans to downgrade the position of the police commissioner.
Sources say the government aims to change the constitutional provisions which define the police commissioner's status and make the office holder answerable to the prime minister.
The sources say the proposed amendment would require at least seven opposition members to join the ruling coalition to have the numbers for a successful vote.
Last December, the government declared the then police commissioner, Shane Castles, an undesirable immigrant following a controversial probe into the government's role in allowing a fugitive Australian lawyer, Julian Moti, into the country.
Mr Moti was to take up the position of attorney general but is wanted by Australia ona child sex charge.
