Rather than starting with an article, I would try to think more broadly - what are general trends or changes that are happening that are impacting businesses generally?
I sense you are starting with an article and trying to get the answer to fit the question, rather than trying to think about what the biggest challenges are and then using sources to back up your thinking.
If you were to use this example, then you would have to start of with why having less regulators is a challenge for law firms. If anything, it could be argued that having more regulation could create more challenges for firms rather than the other way around, so I think you need to frame it upfront around why less regulation would create a challenge. That being said, regulatory lawyers would say it is a challenge as less work would be coming their way, while the transactional and dispute lawyers would probably love less regulation to make their jobs a little easier/bring more work their way!
Also, is the article you are talking about may be in relation to the Business Secretary's comments yesterday that there may be "too many regulators"? If that is the case, you also need to consider how you are using this as it is not anything certain at the moment, it is just that the UK Government is scrutinising current regulatory bodies for not helping the UK's growth strategy, rather than any concrete changes to regulation in the coming months/years.
