As answered here :- How to set default value for ASP.NET MVC DropDownList from model

You can't set the default value using Html.DropDownList, if you want to have a default value, the property itself should have a default value.

 private string country; 
 public string Country
 {
  get { return country ?? "UK"; }
  set { country = value; } 
 }

Then, when the drop down list renders, as long as "UK" is actually a value for one of the options, it will be automatically set to that.
