The row over extending free school meals over the school holidays has continued into its second week.
The UK government has defended not extending the scheme over the half-term holiday. It says it is supporting families through extra money for universal credit and additional funding for councils.
But how many pupils can claim free school meals, and which parts of the country have the highest rates?
In England, children living in households on income-related benefits (such as universal credit) are eligible for free school meals, as long as their annual household income does not exceed £7,400 after tax, not including welfare payments.
This is the same in Wales and Scotland, however in Northern Ireland the cap is set at £14,000 a year.
If a child is eligible, their parent or guardian can claim at any age – from pre-school to further education.
In England and Scotland, all infant state school pupils (those in Reception and in Years 1 and 2) can get free school meals during term time – regardless of their household income.
As of January 2020, excluding year groups where eligibility is universal, 1.4m children qualify for free school meals in England – or 17.3% of the student population.
This is the highest proportion of children eligible in at least a decade.
In Scotland, the equivalent figure is 89,000 primary and secondary pupils – or about 17% of pupils.
In Wales, 20% of pupils are eligible for free school meals and in Northern Ireland it is 28% of pupils.
The proportion of children eligible varies considerably across the country, but generally matches recognised trends surrounding regional deprivation and wealth.
For example, almost a quarter of pupils in the north-east of England are eligible compared with about 13% of pupils in the south-east.
The highest proportion of students eligible for free school meals – about a third – in England are in:
Meanwhile, the lowest proportion of pupils eligible – fewer than one in 10 – are in:
Some groups are more likely to be eligible than others, including some ethnic minorities.
For example, more than 60% of Irish Traveller pupils taking their GCSEs are eligible for free school meals.
Roma/Gypsy, Bangladeshi and black pupils also have disproportionately high eligibility.
Meanwhile, white, Indian and Chinese pupils are far less likely to be eligible for free school meals.
According to the Department for Work and Pensions, an estimated 4.1m children live in relative poverty in Great Britain.
However, fewer than two million pupils across Scotland, Wales and England are eligible for free school meals.
But these two numbers are ultimately showing two different things.
Relative poverty is calculated by taking the median income – that’s the income where half of all households earn more and half earn less – and then looking at how many children live in households earning less than 60% of this.
Meanwhile, free school meal eligibility is a measurement of how many school-age children are living in households claiming some form of employment-related welfare benefit.
Some households in relative poverty might not meet the financial threshold to claim certain benefits.
Both relative poverty and free school meal eligibility are measurements of income rather than food insecurity – although the two are closely linked.
In the UK, there is no single measurement for hunger.
However, a report by the House of Commons Environmental Audit Committee from 2019 looked at different measurements in a report on food insecurity.
None of these measurements are perfect, but shine some light on the scale of the problem.
This is likely – especially since it is based on those claiming welfare.
We know that in Great Britain, the number of households with children claiming universal credit increased by about 45% between January and May 2020.
However, not all of the additional 500,000 households with children claiming the benefit will be eligible for free school meals, due to the £7,400 cap.
