The Solomon Islands prime minister, Sir Allan Kemakeza, says there is no pressure on his government following last week's arrest of the agriculture minister, Alex Bartlett.
The minister, who was made the foreign minister after the 2001 election, is in remand on criminal charges, including arson dating back to the year 2000.
Bartlett has not been replaced.
Another minister, Daniel Fa'afanua, has been in jail after he was arrested by the Regional Assistance Mission for extortion.
Sir Allan has declined to say whether he was concerned that more ministers could be detained but added that no one was above the law.
