Angela Rayner makes a feature of her poor upbringing. Snobbery is cited; there is certainly plenty of inverted snobbery on this thread.
The assumption that:
There is some snobbery about northerners from some. If they haven't lost their accent then they are looked down upon.........
..... resentment from some that she has "overstepped" boundaries and not stayed in "her place", as they see it....it unsettles them.
Nonsense.
My parents came from Manchester, left school at 14 and had accents all their lives. Never held them or their families back.
What horrifies 'some people', is Angela Rayner's ignorance, lack of education, and the fact that she has no intention of remedying it.
There is no comparison other than hair colour between her and the well-educated, intelligent and ferociously hard working Barbara Castle; she is nothing like 'Red Ellen' (MP for Jarrow) who also came from a very impoverished background but fought tirelessly to improve her education, ending her career as Minister for Education 1945. John Prescott had few educational qualifications but studied at Ruskin College and Hull University; John McDonnell studied A levels at night school then for a degree from Brunel University. There are many more.
Rayner has gained her prominence in Parliament purely due to the influence of the Unions, not by her abilities and at present Starmer cannot upset them.
