But 230,000 more people came to live in the UK than left in the 12 months after the EU referendum, new figures released by the Office for National Statistics (ONS) show.
It is a fall of about one third from the 336,000 recorded at the same time last year and the biggest plunge since stats were first compiled in 1964.
Figures showed more than three-quarters of the fall was down to a decline in net migration from EU countries.
People from rich EU nations like France, Germany and Spain saw the biggest declines, with less Poles also arriving on Britain’s shores.
And overall, there were 80,000 fewer people coming to live in the UK in the year to June this year.
There has also been a fall by 43 per cent of the number of people immigrating here to look for work.
The ONS said it was also partly due to a 19 per cent fall in the number of EU citizens coming to find employment.
That may have been partly driven by economic changes elsewhere in the bloc and a fall in the pound’s value.
But Nicola White, the ONS head of migration statistics, said the falls were also driven by the Brexit vote.
She said: “Over three-quarters of the fall in net migration was accounted for by EU citizens.
“The decline follows historically high levels of immigration and it is too early to say whether this represents a long-term trend.
“The number of people immigrating for a definite job has remained stable.
“But there has been a 43 per cent decrease in the number of people immigrating to look for work over the last year, especially for EU citizens.
“These changes suggest that Brexit is likely to be a factor in people’s decision to move to or from the UK.
“But decisions to migrate are complex and other factors are also going to be influencing the figures.”
But she admitted that net migration overall had only returned to levels seen in 2014 following a peak in the middle of 2016.
She said: “Overall more people are still coming to live in the UK than are leaving and therefore net migration is adding to the UK population.”
Despite the decline, further figures showed there had been a huge jump in the numbers of EU citizens applying to become British citizens.
Applications stood at 28,500 in the 12 months after the referendum – a surge of 80 per cent on the previous year.
