How Long will Theresa May Be Prime Minister?

On the 13th July Theresa May will become the 13th Prime Minister to serve under Queen Elizabeth II. I thought i would take a look back at the other 12 and see how long they lasted in office and see how long Theresa might last. Seems like less than a year is the low point to beat, and 11 and half years in the record. This is a simple gantt chart using two dates and a datediff calculation. The donut chart was made using the tutorial on Andy Kriebels blog here http://www.vizwiz.com/2014/12/donutcharts.html
