Reality Check

Claim: In his opening statement Adam Price, the leader of Plaid Cymru, claimed that in Wales a "third of our children [are] living in poverty".

Verdict: He's roughly correct, according to the official government figure, external.

Child poverty, on this measure, is defined as coming from a household that has income below 60% of median income (that's the one you get if you ranked every household in the country in order of income and take the middle one) after housing costs.

The figures show that 29% of children in Wales were in poverty in 2017-18, a rise of one percentage point compared with the year before, although it had been at higher levels for most of the previous decade.

The corresponding figure for England was 31% (reflecting higher housing costs) up from 30% a year earlier.

Boris Johnson said under EU law "you cannot ban the shipment of live animals". Is he right?

Reality Check

Boris Johnson has said that after Brexit: "We will back British industry by making sure we can intervene when great British businesses are struggling."

It is true that the EU takes steps to limit the amount governments can support their industries.

But within the EU, the UK ranks very low down in the amount it spends on state aid, spending 0.4% of GDP (the total value of everything produced in the economy), compared with 1.3% from Germany and 0.8% from France.

So EU single market rules are not the only thing limiting state aid.

After Brexit, the UK would still be bound by World Trade Organisation rules, which allow countries to take sanctions against other countries that are spending too much on supporting their domestic industries.

Jo Swinson said: "We need to make sure that now we have a target for all new-build homes to be zero carbon and to have those high standards. And the Conservatives who can't be bothered to turn up tonight scrapped those plans."

Plans to make all UK homes zero-carbon were first proposed by Gordon Brown in 2006, and cancelled by the Conservative government in 2015.

Zero-carbon homes have better energy efficiency standards, and generate all the energy they need onsite through solar panels and suchlike.

The justification for the move was to reduce regulations on housebuilders, which would have made it harder for the government to meet its targets for home construction.

The following year, the Mayor of London put in place a zero carbon standard for homes in the city.

Nicola Sturgeon said: “We need more support for onshore wind which the Tories disgracefully have taken away.”

It is true that onshore wind installations in the UK last year were at their lowest since 2011, at 598 MW of generating capacity. That followed a bumper year in 2017, when 2,666 MW were installed, according to Renewables UK, the industry group.

It blamed the peak in 2017 and the subsequent downturn on government policy. 2017 was the last year of the renewable obligation scheme, which supported many large scale renewable projects.

Also, it said onshore wind projects are not able to bid for subsidies under another renewable support scheme, contracts for difference.

In addition the Conservative government changed the planning rules to give local councils in England more powers to block new wind farm schemes.

Overall, however, the UK has made impressive progress in decarbonising its electricity generation, helped among other things by a big increase in offshore wind generation.

According to Carbon Brief, since 2008 “the UK has cleaned up its electricity mix faster than any other major world economy.”

Labour leader Jeremy Corbyn said: "We have the lowest level of tree cover of almost any country in Europe."

That's right - 13% of the UK is covered by trees. One country in Europe with a lower level is Ireland at 11%.

Malta has almost no tree coverage

The EU average is more than 30%.

Jeremy Corbyn says that "Just 100 companies are responsible for 70% of emissions."

This claim features in a report by the Carbon Disclosure Project from 2017, external. This report looks at industrial carbon dioxide emissions only, and not global warming caused by agriculture use or deforestation.

It also only looks at which companies produce the fossil fuels - unsurprisingly they are mostly oil and gas companies. It doesn't look at the end users such as airlines, or indeed consumers.

Green Party co-leader Sian Berry said reducing the amount of flying: "does mean targeting those 15% of people who take 70% of all flights".

That figure is based on analysis by a group calling for a frequent flyer levy of a government survey, external carried out in 2014.

It found that 52% of people had taken no flights in the past year, 22% had taken one, 11% had taken two and 15% had taken three or more.

The published figures do not break down far enough to confirm the claim, but researchers from Full Fact , externalspoke to the Department for Transport, which confirmed that a more detailed breakdown of responses suggests that those 15% of flyers made 70% of the total flights.

SNP leader Nicola Sturgeon said: "Scotland is already leading the way, we have almost halved our emissions."

That claim was supported by Scottish government statistics, external in 2018, which showed levels in 2016 were 49% below the 1990 baseline, following a 10.3% drop on the previous year.

Much of that year's drop was attributed to the 2016 closure of the Longannet power station.

But the more recent figures , externalshowed that by 2017 emissions were 47% down from 1990.

Boris Johnson said earlier that Nicola Sturgeon told the BBC’s Andrew Neil last night she wanted Scotland to join the euro.

Commenting on the SNP’s referendum plans, Mr Johnson said: “With their crazy policies, I think confirmed last night as I understood it to Andrew Neil - did I get that right? - confirmed to rejoin the EU, to join the euro.”

While the first minister did confirm that she wanted an independent Scotland to rejoin the EU (should Brexit happen), she did not say she wanted Scotland to join the euro.

In fact, Ms Sturgeon said she wanted to keep the pound until a time when Scotland could introduce its own currency. Her exact words were: “Firstly the pound is Scotland’s currency right now.

"The proposition is that until the conditions were right to establish our own currency which we’ve said would be our objective, then we would use the pound to do that.”
