Your first point has always interested me, as it's unclear how much technical expertise these people have. They just employ Special Advisors to do the 'difficult' work for them (again, something not included in their expenses but, of course, is a benefit). And the manner in which reshuffles happen when the Education Secretary suddenly becomes the Enviroment Secretary whilst having no experience of either.
Anyway, I'm very sure there are good MP's, but I'll not go so far as to say these people are underpaid.
I plugged the question into AI ... see below. Not to mention the subsidised "everything". Holidays in mates villas (and what mates, eh). The "director" positions on various companies, and, and ... it's not just the monetary value of these things. It's an absolute gravy train.
Generated Hypothetical Answers:
we can provide some hypothetical scenarios based on varying levels of responsibility:
Scenario 1: Backbench MP without additional roles:
Salary: £86,584
Maximum Expense Claims:
Office: £85,000
Accommodation (Constituency only): £9,300
Travel: Assuming moderate travel expenses, let's estimate £10,000
Other Expenses: £5,000
Total: £86,584 + £85,000 + £9,300 + £10,000 + £5,000 = £195,884
Scenario 2: MP with Ministerial role and chairing a committee:
Salary: £86,584 + Ministerial salary (e.g., £50,000)
Expense Claims: Similar to Scenario 1, let's use the same estimates
Committee Chair allowance: £11,600
Total: £86,584 + £50,000 + £85,000 + £9,300 + £10,000 + £5,000 + £11,600 = £257,484
Remember: These are just hypothetical examples, and the actual value for any individual MP can be significantly higher or lower depending on their specific circumstances.
