Delete " OTHER " calendar

Hi guys can anyone help me.

In my calendar app I have a calendar that I want to get rid of.
It's a UK holidays calendar that is showing in OTHER alongside my birthday calendar. Underneath the calendar it says " subscribed " but I don't have any subscribed calendars. If I click on the information icon at the side of the calendar I only get the option to change the colour. I would really like to delete it if possible so any help would be appreciated.


PS :- I don't sync calendars with iTunes.
