The ITV Leaders' Debate, fact-checked

Around £8 billion in government payments goes to private landlords every year, according to Green co-leader Caroline Lucas.

Ms Lucas is right.

This year about £8.8 billion in housing benefit will go to private landlords, via tenants renting privately.

It’s been more in previous years.

Around 3% of grammar schoolchildren are eligible for free school meals, according to Liberal Democrat leader Tim Farron.

At the start of 2016, fewer than 3% of students in grammar schools were eligible for free meals, compared to 14% for all school types, Full Fact explain.

In other words, the poorest children are considerably less likely to get into grammar schools.

And that’s not just down to differences in ability.

“Amongst high achievers, those who are eligible for free school meals or who live in poorer neighbourhoods are significantly less likely to go to a grammar school,” the Institute for Fiscal Studies report.

The government argues that children from families earning below the average income - even if they’re not the very poorest in society - do attend grammar schools.

Around 500,000 schoolchildren are in classes bigger than 30 pupils, according to Ukip leader Paul Nuttall.

That’s correct, Full Fact say.

More specifically: around 540,000 primary school pupils in English state-funded schools were in classes with 31 or more pupils in January 2016.

So too were about 300,000 secondary school pupils.

The Conservative economic plan was meant to eliminate the deficit in five years, but now we’re told it will take two decades, according to Plaid Cymru's Leanne Wood.

She also claimed the UK’s debt has increased by £555 billion since the Tories came to power.

The government set deficit targets in 2010 (which it didn’t meet) and in 2015 (which it abandoned), Full Fact explain.

As a result, UK government debt has continued to rise.

We haven’t immediately been able to replicate Ms Wood’s exact figure, but it’s in the right ballpark.

Even adjusted for inflation, public sector net debt rose £450 billion between 2010/11 and 2015/16, according to the Office for Budget Responsibility.

Britain's foreign aid budget costs around £30 million every single day, according to Ukip leader Paul Nuttall.

The UK’s foreign aid budget in 2016 added up to £13.3 billion, Full Fact say.

That’s even more per day than Mr Nuttall claims - around £36 million per day. The 2015 budget was closer to his figure.

The budget rises in line with the size of the UK economy, as we aim to meet a UN target of 0.7%. Mr Nuttall was correct to say that the United States is nowhere near meeting this - it typically spends only 0.2%.

Around 95% of all private sector involvement in the NHS came under a Labour government, according to Liberal Democrat leader Tim Farron.

Private sector involvement in the NHS has been increasingly steadily under all parties.

About 7.6% of NHS revenue spending in 2015/16 went on purchasing care just from private providers, according to Department of Health accounts.

If you include all non-NHS providers then this goes up to 10.7%.

Immigrants make a huge contribution to the UK economy, according to Green co-leader Caroline Lucas.

The impact of immigration on public finances is relatively small according to most studies, costing or contributing less than 1% of UK GDP, Full Fact say.

Immigrants from the European Economic Area and recent immigrants are more likely to have a positive impact (or less likely to have a negative impact).

No overall figure necessarily represents the experiences of any individual or local area: for example immigration's public service impacts vary by region.

More than 80,000 jobs in Scotland could be at risk in the event of no deal at the end of Brexit negotiations, according to SNP leader Nicola Sturgeon.

Most economists agree Brexit will see fewer jobs being created and some jobs lost, fact-checking charity Full Fact say.

As for what happens to Scotland, one set of forecasts for the Scottish parliament did estimate that ten years after Brexit, there would be 80,000 fewer jobs in Scotland than there would have been.

But this isn’t a figure for how many individuals would lose their jobs - rather it’s how many fewer jobs there would be in the economy.

Four million children in the UK are currently living in poverty, according to Green co-leader Caroline Lucas.

That’s the correct estimate for 2015/16 looking at ‘relative poverty’ once housing costs were taken into account, fact-checking charity Full Fact believe.

This hasn’t changed significantly in recent years.

Relative poverty looks at households with less than 60% of the median income that year. There are other ways to measure poverty, though, which give you different figures.

Factchecking charity Full Fact join ITV News for Thursday's televised leaders' debate.

Full Fact will be listening in and analysing claims made by the party leaders, comparing them to their own independent research.
