Can they do that? Sunak, Rwanda and Cameron

 This has been a tumultuous week:

- Suella Braverman has been sacked as Home Secretary after her comments about the Palestinian marches and the response from the Metropolitan Police to these and other protests, which were deemed to have inflamed the issue and led to serious disorder over the weekend. Braverman has since released a letter dripping with criticism of the Prime Minister.

- David Cameron has mounted a sensational political comeback - after resigning as an MP in 2016, he is now in post as Foreign Secretary, a role that he will perform from the House of Lords.

- The Government's Rwanda policy, where asylum seekers are sent to Rwanda while their claims are processed, was deemed to be illegal by the Supreme Court (not, as Sunak claimed in a post on Wednesday evening, a 'foreign court).

- Rishi Sunak has said he will pass emergency legislation in order to declare Rwanda a safe country.

Let's step back and consider the importance of two aspects of this from a Politics A Level standpoint; can Cameron simply be brought in from anywhere to be Foreign Secretary, and can the government simply override the Supreme Court like that?

In the case of the appointment of David Cameron as both Lord Cameron and as Foreign Secretary, the answer is 'yes, they can.' A lot of how our constitution works, in terms of appointments, is based on convention. After all, it hasn't been that long since Prime Ministers operating from the House of Lords was common! (well, not that recent, but 1895-1902)

There is always one representative of the House of Lords in the Cabinet in any case, but all major posts are regularly held by MPs. The most recent example that springs to mind is when Gordon Brown brought back Peter Mandelson, as Lord Mandelson, to serve as Business Secretary. But Foreign Secretary is another level. The biggest question is how will he held to account - MPs need to be able to question any minister about their actions, and this will not be possible with Cameron in the Lords.

The next question is over the government's Rwanda policy, which has been blocked by the Supreme Court. However, Rishi Sunak has said that he will pass emergency legislation in order to declare Rwanda a safe country. Which, of course, he can do. There may still be other legal recourse, as of course, it is the European Convention on Human Rights, but ultimately the policy will be able to go ahead. There isn't a better example of parliamentary sovereignty in practice!
