Stuart Syvret has been in the UK since October, Jersey's governance is lacking "checks and balances" from external sources, Senator Stuart Syvret has said.
The politician is in a self-imposed exile in the UK after saying he feared he would not get a fair trial for motoring and data protection offences.
The former Health Minister told the BBC the government needs more scrutiny from UK authorities to ensure impartiality.
Chief Minister Senator Terry Le Sueur said more external checks were in place then when Mr Syret was a minister.
Mr Syvret has been in the UK since October and has been staying with Liberal Democrat MP John Hemming, who claimed Mr Syvret was seeking asylum on legal grounds.
'Open investigations'
An arrest warrant was issued for the 44-year-old when he failed to appear at an abuse of process hearing into his arrest for the data protection and motoring offences.
Mr Syvret has questioned Jersey's ability to rule itself.
He told the BBC: "You have to seriously question its capacity to govern itself in a way that is safe.
"Frankly it cannot do that at the moment.
"...I'm not advocating that Jersey's independence be taken away from it, but when it comes to those parts of public administration that are responsible for properly overseeing say the political public services sector and providing those checks and balances for prosecution, police, courts, they must all be completely independent."
Mr Le Sueur said: "Until other ministers were appointed there were no such checks and balances.
"The present [health] minister has introduced, and in fact her predecessors Senator Shenton and Senator Perchard introduced, more open investigations.
"We've got now a Scottish work institute looking at social work, we've got a care equality commission looking at healthcare.
"There's far more questioning going on now than ever when Senator Syvret himself was minister."
