The scheme, announced last month, was intended to offer security to the families of migrant workers if they should die working on the frontline of the pandemic. But it caused outrage after care workers, hospital cleaners and porters were excluded.

It initially only applied to certain occupations in the system including nurses, biochemists and radiographers. The GMB union had described it as an ‘outrageous scandal’ which left low-paid workers ‘out in the cold’.

However, the Home Office made the U-turn moments after the daily No 10 press briefing on Wednesday, during which NHS England’s national director, Stephen Powis, insisted there are a ‘huge number of people working behind the scenes’ in hospitals who often don’t get praised.

The scheme will now include cleaners, porters, social care staff and care home workers and will come into effect immediately and retrospectively, said officials.

Home Secretary Priti Patel said: ‘Every death in this crisis is a tragedy, and sadly some NHS support staff and social care workers have made the ultimate sacrifice in the pursuit of saving the lives of others.

‘When I announced the introduction of the bereavement scheme in April, I said we would continue to work across Government to look at ways to offer further support. Today we are extending the scheme to NHS support staff and social care workers.

‘We want to ensure families have the support they need and so this will be effective immediately and retrospectively.’

Hours before the announcement, hospital cleaner Hassan Akkad called on Boris Johnson to extend the scheme in an impassioned Twitter video.

The Bafta award-winning filmmaker from Syria said although he had been ‘enjoying the clapping’ that ministers do every week, he felt let down when he learned his partner wouldn’t qualify for the scheme.

He said: ‘Today, however, I felt betrayed, stabbed in the back.

‘I felt shocked to find out that you’ve decided, your government decided, to exclude myself and my colleagues who work as cleaners and porters and social care workers who are… all on minimum wage, you’ve decided to exclude us from the bereavement scheme.

The Home Office’s move came after Professor Powis paid tribute to all NHS and care workers during today’s Downing Street press briefing.

He said: ‘All I can say is, as a doctor who has worked on the front line for many years, how much I value the entire multidisciplinary teams – so everybody from porter to manager to administrator to nurse who absolutely work together as a team in managing this sort of crisis but also in the day-to-day care that the NHS provides.

‘It’s often the doctors and nurses who are at the front and get the praise but believe me there are a huge number of people working behind the scenes.’

The news comes as Yvette Cooper, chairwoman of the Commons Home Affairs Committee, raised concerns about care workers and low-paid NHS staff not being included in the Home Office’s free visa extension scheme.

Ms Cooper said: ‘It is really disappointing to get confirmation from the Home Secretary that care workers and low-paid NHS staff are not included in the free visa extension scheme even though we had asked the Government to rethink.

‘This means care workers applying to renew their visas along with the NHS surcharge could end up paying thousands and thousands of pounds.

‘Asking them to do this as they stand on the UK front line against coronavirus, caring for and supporting people, and putting their own health at risk feels deeply unfair.’

Last month, the Government said it was expanding a scheme to help NHS workers so that migrant midwives, social workers, pharmacists and other frontline health staff will be granted free visa extensions for a year.

All visas for the health workers in question which are due to expire before October 1 will be automatically renewed for a year.

The Home Office said it ‘will apply to those working both in the NHS and independent sector and include their family members’.

Those who qualify will also be exempt from the immigration health surcharge during the extension.

But the measures are unlikely to extend to carers working in small private care homes because the Home Office said such staff were more likely to be working in the country on a long-term visa, which allows them to work, rather than having a time-limited shorter-term sponsored work visa.
