Just watched his justification & reasoning behind the extra bank holidays (on Andrew Marr):
"People need to have more time to spend with their families".
"The BofE have said that costwise it won't be detrimental as people spend more on bank holidays as they're out & about"
I was left bemused as to why Andrew Marr didn't ask the most obvious question:
Where are these 'people & their families' spending their money??!!
In shops/cafes/etc where.......people are working? 

Stupid, stupid, stupid.
Make 30 days standard annual leave compulsory (with bank holidays on top) and that makes sense.
4 forced days? Madness.
