A father-of-three who confronted David Cameron for allowing mass immigration to turn areas of the country into ‘no-go zones’ yesterday accused the Prime Minister of having no plan to deal with the problem - and insisted if we stay in the EU then all Brits should flee the country.

Harry Boparai, a 41-year-old British Airways worker, said he would vote to leave the EU after Mr Cameron failed to explain how he would tackle his concerns while the country remains a member.

In a live television debate on Tuesday night, Mr Boparai told Mr Cameron he was unable to get a GP and could not get on to the housing ladder because of rising numbers in his local area.

Mr Boparai, who lives in Ashford, Surrey, said he felt let down after voting Tory at the election last May because of Mr Cameron’s pledge to cut immigration.

But a red-faced Mr Cameron was unable to tell him how he planned to reduce numbers to a manageable level while the country remained a member of the EU.

Mr Boparai, whose parents moved to Britain from India in the 1960s, yesterday told the Mail: ‘I’m now more of a Brexiteer. I feel like he sidestepped my question and I didn’t get the answer I expected.

‘I was hoping for more of a constructive plan about how he was going to deal with the influx.’

At the election, Mr Cameron promised to reduce net migration to the tens of thousands, but Mr Boparai said the last year had shown this is impossible without leaving the EU.

‘The morning of the General Election I wasn’t too sure who I was going to vote for,’ he said.

‘It’s frustrating because I’m doing 80 hours a week to feed my kids and keep a roof over their heads. This is not where I visualised being at this age.’

He added that the migrant situation is now so out of control that he feels 'there’s no future' in Britain for he and his family - and he will 'even tell my own kids to leave the country if we stay in.'

Mr Boparai’s parents came to Britain from India in 1963, but he said the area around where he grew up in Hounslow, West London. had been changed hugely by uncontrolled numbers of arrivals in recent years.

His father, who worked in financial services, had planned to return to his home country with his wife and six children in the 1980s, but decided to stay in London as his children could not cope with the heat when they went back to visit.

A row of shops around the corner from his parents’ five-bedroom detached home includes a number of foreign shops. including an Eastern European supermarket where few staff speak English.

In the television debate, Mr Boparai asked Mr Cameron: ‘I have no GP as all are full in my area. I can’t get onto the housing ladder and have three kids in one room. The place where I grew up was a lovely area but is now a no go zone.

‘How is the EU and uncontrolled immigration working for me, a 40-year-old Brit who has been working full-time since the age of 16?’

Mr Cameron replied: ‘Well what I would say is I think there are good ways of controlling immigration, and I think there are bad ways.

‘A good way, I think, is saying that people can come here. They can work, they can contribute, but they have to pay in before they get out.

‘But I would say frankly that if we want to build houses, if we want to invest in our health service, if we want good schools for our children, we’ve got to strengthen and safeguard our economy.

‘And pulling out of the single market, which is what the Leave campaign want to do, that would damage our economy.’

But to loud applause from the rest of the audience, Mr Boparai responded: ‘Sorry Mr Cameron. I voted for you in the last election because one of the things on your manifesto was to get immigration down. You haven’t been able to do that because you’re not allowed to do that. That’s the bottom line.

‘I’ve seen my standard of living and my family’s standard of living go down because of this influx that we cannot control.

‘I’m sorry to say but your closing statement last week was, “if we leave the EU, we’re rolling a dice with our children’s future”. I think quite the opposite. By you telling us to stay in, you’ve rolled that dice already.’

At Mr Boparai’s small first-floor flat, he and his partner Laura, 33, have had to put bunk beds in the second bedroom for his children.

The terraced home, which is close to Heathrow Airport where he works in British Airways’ reservations department, is just two miles from a doctors surgery where the Mail 18 months ago found up to 30 patients were being forced to queue outside at 7am in the hope of getting an appointment.

The population just a few miles away in Hounslow, where Mr Boparai grew up, has grown rapidly - leaping by a fifth in the decade between the last two censuses from 212,000 in 2001 to 254,000 in 2011.

Sheila O’Reilly, a Hounslow councillor, yesterday said there were parts of the borough that she now would ‘not be happy going even in daylight’ and said the surge in population had put pressure on local services.

Up to 20,000 sheds and outbuildings in the suburb’s back gardens are thought to have been illegally converted into so-called ‘beds in sheds’ to help accommodate newcomers.

‘A lot of GP surgeries have closed their books to new patients so some people have to go and see a doctor out of their own area or some just go to A&E,’ the councillor said.
