Freedom of Information request

Inspired by George Osborne:

Dear Her Majesty's Treasury,

I would like to know:

1. What definition does the Treasury use to determine whether someone has "made the lifestyle choice" to "sit on out-of-work benefits"?

2. Who is responsible for deciding whether or not someone has made the lifestyle choice to sit on out-of-work benefits?

3. How many people are currently "making the lifestyle choice to sit on out-of-work benefits"?

4. How long does the Treasury estimate it will take to ensure that the money will not be there to fund this "lifestyle choice"?

Yours faithfully,

Don Paskini
