Meanwhile, those with investments or property in France face an anxious wait as the full implications of the blacklisting emerge.

It is understood that those who sell any asset, such as a second home, and want to take the money out of France might be required to pay tax of up to 75 per cent.

Jersey’s foreign minister, Senator Sir Philip Bailhache, has arranged to speak to the French Ambassador and senior government representatives are to speak to the French finance ministry.

Senior ministers have also been in touch with the Ministry of Justice in London, which is responsible for Jersey relationship with the UK, to discuss the blacklisting.
