The Solomon Islands' Political Parties Commission has warned political parties may be suspended if MPs don't comply with the Political Parties Integrity Act.
A spokesperson for the Prime Minister Manasseh Sogavare says seven ministers in the coalition government have resigned from their posts.
The Commission says it has not received formal notification that any MPs have resigned from their political parties.
The Registrar of Political Parties, Calvin Ziru, says until the documents are submitted the Government Coalition Agreement still stands.
He says if breaches are made to the Integrity Standards in the act the Commission could progress towards suspension.
He says the parties are responsible for ensuring their MPs do not compromise the party.
The Commission says all party executives and MPs should comply with the provisions of the law.
