BRP renewal vs citizenship

You don't need a lawyer, I'll write it for you (Pro Bono):
"Approximately 20 years ago I received a fixed penalty notice for a minor traffic accident.  I paid it. "
That's what mine looked like, except a little longer and more colourful,  and I got my citizenship just fine.

He's not joking.  This is literally the level of detail you need to provide. 

Nothing has changed recently. It's been over a century since the UK has been been able to able to remove or renounce the British citizenship of those who applied to be a British citizen.

The last big change was in 2005, when the the Labour government brought in  laws so that those who are born a British citizen can also have their citizenship removed if they have another citizenship. Amended in 2014 (?) to, if the HS thinks they have a claim to another citizenship.

I should have added that the other recent big change was for EEA citizens and the non-EEA citizens who used these EU routes to the UK and to British citizenship. With the UK ending the EU's Free Movement of Persons to the UK, it appears that these people  will now come under the UK's much stricter, amended Immigration Act 1971 of, once citizenship is removed, that person cannot have their ILR back. While the UK was in the EU, the EU allowed people to  live in the UK under their rules, even though the UK immigration rules would not have allow them to do so.
