The current conservative government is on its last legs before being banished for at least a decade. It appears they already have their eyes on the lucrative private sector and are willing to vandalise the UK with little thought to public protest.
Kshama Sawant is a leftist. There are folks left of her.
If you don't see Biden as centrist or even center right, you have a narrow view of the spectrum.
Our major parties are now squashed into the spectrum between the mean US Democrat and the mean US Republican, it's quite depressing.
The UK courts are currently weak because the government threatens their independence. But the same thing is happening in other countries such as Israel, so it’s not something that a written constitution can prevent. Ultimately the only thing that can guarantee judicial independence is for people to believe in it, and for people to take to the streets. Most British people just don’t care, that is the problem.
The Supreme Court exists for this very purpose, although it is subject to Parliamentary Sovereignty[0].

Bills do not become law until given Royal Assent by the King. The King may refuse to give Royal Assent to any bill, although this has not been done since 1708.[1]

The USA is in a position where it seems to be perpetually stuck in a 50/50 split of the elected government, so it's not possible for major constitutional reform to be passed by one party.
On the other hand, the current government in the UK has a majority of 80 MPs - if there was a written constitution, it's likely they could simply pass a law to re-write it.
Personally I quite like it. Evidence suggests there’s quite a lot of people trying to blow us up and stuff.
