As of March 2020 our UK members of Parliament have voted and succeeded in recieving a 3.2% pay rise - above inflation - equal too just under £82,000. 

They also receive a large amount of tax payers money in the form of expenses for travel, food and drink. 

As of 2019 the National Minimum Wage (minimum amount paid to an employee by law) for 25+ is £7.83 per hour whilst the National Living Wage (recommended pay based on inflation and other factors) is predicted to be £8.57 for 2020. 

MP are now being paid £82,000 per year plus expenses whilst if you're 25+ working 40 hours a week on the April 2019 minimum wage of £7.83 you will only receive £14,610.59 (after tax/no benefits).
I propose any rise in our MPs pay - OUR PUBLIC SERVANTS - should mean the public can receive an increase as well. After all it means we have a larger disposable income to stimulate the economy and if we earn more we can pay more taxes. (Win win)

It is no secret the current minimum wage is not capable of meeting a persons needs due to the harshness of Austerity, severe cuts to public services, privatisation, and decrease in wealth distribution. 

Institute of Fiscal studies had this to say in June 2019:

"We examine the reason for the increased in-work relative poverty rate in Britain over the last 25 years, which has risen by almost 5 percentage points from 13% to 18%. We identify two reasons that are actually due to positive trends in British society: the catch up of pensioner incomes (driven by higher state and private pensions), and falls in worklessness bringing low earning types of households (such as lone parents) into work. We show that increases in household earnings inequality since 1994 explain 1.4 percentage points of the rise. The fact that housing costs have risen much more for low income households than for higher income households explains 2.4 percentage points of the rise. Working against this, increases in re-distribution towards low-income working families pushed down relative in-work poverty by 2.1 percentage points. This was due to benefit changes in the early 2000s and between 2007 and 2010 which acted to reduce relative in-work poverty, though this has been partially reversed by reductions to benefit entitlements since 2010."

I would like to propose that any increase in our public servants pay should trigger a further increase of our minimum wage. Increases in the public purse will only make it easier to pay taxes which help us afford public services and servants such as Members of Parliament. 

Increases in pay would reduce use of food banks, in work poverty and child poverty.

In its mid-year statistics the Trussell Trust reported a 23% rise in the number of food parcels they distributed in April to September 2019, compared with April to September 2018. The figure rose from 658,048 to 823,145 parcels. This is the steepest increase it has recorded for five years. Around a third of these were requested for children. - house's of commons: https://commonslibrary.parliament.uk/social-policy/welfare-pensions/what-do-the-latest-food-bank-statistics-tell-us/
