Problem: But Eluned Morgan conceded that it would be "difficult for us to stop" from a legal point of view. Her comments were criticised by a Labour AM. Alun Davies said threatening legal action "sounds like the last breath before you're thrown out of the pub". Mr Davies said he was not convinced the Welsh Government would "have a leg to stand on" in trying to shape international trade deals after Brexit. Following Donald Trump's comments during last week's trade visit that the NHS would be "on the table" in any future trade talks between the UK and the USA, Eluned Morgan said there was "absolutely no prospect whatsoever of us allowing the Welsh NHS to be part of any negotiation." The US President then rowed back on his initial comments following criticism from a number of MPs. Asked about her response to President Trump's remarks as she gave evidence to the Assembly's Brexit committee on Monday, Ms Morgan said "legally, it would be difficult for us to stop because we don't have a veto over trade". "Politically, I think it's extremely unlikely to happen," the international relations and the Welsh language minister said. "They [the UK Government] should not be concluding any trade agreements without consulting us where we have the power." Ms Morgan explained that UK and Welsh government officials are working on an agreement or 'concordat' for how future trade deals are negotiated. During a robust exchange, the Labour AM Alun Davies said: "I want something which is in law to which I can hold you to account and which colleagues in Westminster can hold the UK Government to account. "The argument we'll make life difficult for them, it sounds alright on the street, but it's not the reality of intergovernmental relations." "The United Kingdom has to find a way of functioning. "At the moment, your answers aren't giving me any confidence that there is that structure in place because, if the Welsh Government's argument is, 'we'll see you in court', it's not a very impressive argument either for the continuation of the structure of United Kingdom as a state or the commitment of the government within the United Kingdom to actually work together," he added. Responding to the criticism, Ms Morgan said: "Is the current intergovernmental structure adequate? "Absolutely not... and it's not just in relation to trade, it's in relation to almost every aspect of government policy. So, that infrastructure needs to be built."

Problem: By Lora JonesBBC News So, how much is being spent on e-cigarettes, and how safe are they? 1. Vaping is increasingly popular According to the World Health Organization, there has been a small but steady decrease in the estimated number of smokers globally, to just over one billion. But it's a different matter when it comes to vaping. The number of vapers has been increasing rapidly - from about seven million in 2011 to 41 million in 2018. Market research group Euromonitor estimates that the number of adults who vape will reach almost 55 million by 2021. 2. Spending on e-cigarettes is growing The e-cigarette market is expanding, as the number of vapers rises. The global market is now estimated to be worth $19.3bn (£15.5bn) - up from $6.9bn (£5.5bn) just five years ago. The United States, United Kingdom and France are the biggest markets. Vapers in the three countries spent more than $10bn (£8bn) on smokeless tobacco and vaping products in 2018. The White House recently announced that the Food and Drug Administration (FDA) would finalise a plan to stop the sale of all non-tobacco flavours in the world's biggest vaping market. This follows six deaths and 450 reported cases of lung illness linked to vaping across 33 US states. 3. Open system e-cigarettes are the most popular There are two main types of e-cigarette - open and closed system, also known as open and closed tank. In an open system, the liquid that is vapourised can be refilled manually by the user. There is also a removable mouthpiece. Closed system e-cigarettes use ready-made refills, which screw directly on to the e-cigarette's battery. It is reckoned that this year, vapers will spend an estimated $10bn (£8bn) on closed system e-cigarettes, overtaking the spend on open system e-cigarettes for the first time. 4. Most e-cigarettes are purchased in-store Most e-cigarette users buy their devices in specialist shops, according to a 2016 report published by Ernst & Young. It's thought that consumers might make their first e-cigarette purchase in person, to build familiarity with a relatively new product, or to seek advice on which type of device might suit them best. Vaping shops have become more common in the UK, with 69 new stores opening on High Streets in the first half of 2019 alone. Another survey of 3,000 users by Kantar for Ernst & Young, suggested that 21% had bought their devices online. 5. Is vaping safe? In the US, Michigan has become the first state to ban flavoured e-cigarettes, following the reports of deaths and lung illness. Those affected had an average age of 19. However, doctors, public health experts and cancer charities in the UK agree that, based on current evidence, e-cigarettes carry a fraction of the risk of cigarettes. One independent review concluded vaping was about 95% less harmful than smoking. Professor Ann McNeill, who wrote the review, said "e-cigarettes could be a game changer in public health". The UK has much tighter rules on the content of vape pens than other countries like the US. Nicotine content is capped, for example, whereas it isn't in the US. But, e-cigarettes can still contain some potentially harmful chemicals also found in cigarette smoke, although at much lower levels. The World Health Organization has also previously cited several health concerns associated with vaping, pointing out that:
