If the Mayor of London doesn't have significant influence over how budgets are spent on the police and other public sectors and infrastructure in London then we might as well scrape that position altogether. Currently I feel like the Mayor is spending all his time and budget on personal PR and conducting dumb Twitter fights with foreign leaders. I get it, we all hate Trump, but our Mayor should not have to worry about foreign presidents, no matter how dumb these presidents are. The UK has a foreign secretary for that work. The Mayor should entirely focus his efforts and OUR TAX MONEY on the issues which our city has. I hate it that our hard earned tax money is being used for the Mayor to fund his personal PR campaigns to further progress his political career. How is that useful to anyone? And yes, I agree, the government is 100% responsible for cuts to the public sector and that's why all the establishment parties (Tories and Labour) are both in the shits, because they both have failed this country. There's no party I could currently vote for. Tories have literally wasted everyone's time and money for the last couple years with their own Game of Thrones game in their ranks, Labour is just an incognito racist party with Corbyn being dumb and ideological which is a dangerous combination (like Hitler was), Lib Dem and Greens are like a water melon, green on the outside, but red inside, and UKIP is just a disgrace full stop. They are all responsible for the UK's problems, but when I have to point my finger at someone for the problems in London, then the first instance is the Mayor of London.
