Well it appears that between 2020 & 2021, it increased by over £900m per week.
However a large part of that has basically been classed as "extra spending due to covid".
Excluding covid, its also incrceased by £440m per week between 2022 & 2023 (so more than the fabled 350).
The only thing you can factually state is its increased by more £350m per week since 2016 (or indeed, since 2020).
Its impossible to define "extra" as there is no way to know what the budget would have been, its simply increased.
