A London council is demanding more money to manage an influx of hundreds of Chagos Islanders who have recently moved to the UK.
Hillingdon Council has claimed 400 Chagossians, with British citizenship, have arrived from nearby Heathrow Airport in the last year.
The council said supporting the islanders is costing hundreds of thousands of pounds and the government was only providing funding for the first 10 days after arrivals.
Hillingdon Councillor Ian Edwards told GB News on Wednesday it was "clearly not enough".
It comes after the UK Government signed a deal to give the Chagos Islands, a British overseas territory, to Mauritius in May.
The residents of the Chagos Islands were evicted between 1967 and 1973 in order to establish a joint UK-US military base.
"We have spent half a million pounds up until the end of the last financial year in support (of) Chagossians," Edwards said.
"The government have offered us £70,000 pounds in compensation."

GETTYWhen asked by Emily Carver why "we need to be spending so much money" on the Chagossians, Edwards said it was the council's "responsibility for anybody who turns up at Heathrow and requires public assistance".
As the islanders hold British passports, Edwards said they are "lawfully entitled to be in the country".
They however are unable to qualify for support that is afforded to refugees and asylum seekers.
And, while Edwards said the government advises those arriving to make their own housing arrangements, he said "they arrive without having taken that advice".

GETTYHe added that they then "turn to the council for support ... part of that is the accommodation cost".
"It's also just the administration cost and officer time of receiving these people, supporting them and helping them settle into the country," Edwards said.
He claimed the government was "expecting Hillingdon residents to pay" in order to meet the council's obligations of offering that very support.
Edwards had previously told GB News that the government was "failing to support" the council which has seen the "pressures rise quite enormously" since the deal.
The government has said funding was being given where those arriving were "creating immediate local pressures".
A Chagossian who arrived at Heathrow Airport, Rebecca Philippe, was in tears when discussing her homeland's history with the BBC.
She said her late grandmother was a British Chagossian who "50 years ago ... was uprooted from her island".
"By seeing her suffering, we suffered too, with her," she said.
Philippe said "we are here" in the UK to "not only for our rights but to honour her".
She claimed she had to hide her British Chagossian identity in Mauritius as anyone who criticised its sovereignty risked a jail sentence.
A Human Rights Watch report outlined how several Chagossians, who were displaced to Mauritius, had continued to suffer poverty, stigma and discrimination.
Since the government's deal in May, Hillingdon Council said more than 100 Chagossians had arrived at Heathrow Airport in a single week with many arriving without accommodation plans.
The council claimed the arrivals had cost more than £508,000 between July last year and March which was placing an unsustainable demand on its services.
So much so, it has forecast an annual cost of $1.2m with more Chagossians expected to arrive with the global population roughly around 10,000 people, and split between the Mauritius, the Seychelles and the UK.
