The Council of the Isles of Scilly will receive £210,000 from the Government to help with costs caused by Brexit.
The sum is part of a £56.5 million handout to councils over the next two years to prepare for the UK's departure from the EU, along with a pledge that any future costs will be fully funded.
Communities Secretary James Brokenshire announced that English councils will be given £20m this financial year and £20m next year to spend on "planning and strengthening their resources". Unitary councils will receive £210,000, combined authorities £182,000, county councils £175,000 and district councils £35,000.
He also said that a further £10m will be set aside to "respond to specific local costs that may only become evident in the months after we exit the EU", as well as £1.5m to local authorities with ports.
The Minister added that local authorities have a "critical role to play in making a success of Brexit in their areas".
Meanwhile, the Local Government Association said councils are as fully prepared for Brexit as they can be considering the "uncertainty" involved.
Cllr Bentley, chairman of the LGA’s Brexit task force, said: "We are pleased that the Government has confirmed that any additional responsibilities resulting in new financial pressures for councils arising from Brexit will be fully funded."
Cornwall and the Isles of Scilly will be one of the biggest losers of EU funding after Brexit, according to new analysis by the Conference of Peripheral Maritime Regions.
