Make Jerusalem England's Official National Anthem

I want the Government/Parliment to Make Jerusalem Our national anthem as I believe English culture is being forgotten about and is on the border of being neglected. One way to stop this from happening is by giving our country an Anthem that embodies England our wonderful country. I hope by making this our national anthem it will invigorate a wave of English Patriotism the same way Flower of Scotland or Hen Wlad Fy Nhadau did for Wales and Scotland which would unite our country
