POA - Can the DWP look at those accounts?

I've found some information about it from the government website but it's not entirely clear:

Where the bank is aware that there is a Lasting Power of Attorney or legal deputy (a “deputy”) acting on behalf of any relevant account holder, the bank must provide the name and correspondence address of the deputy to DWP following receipt of any information notice, pre-deduction notice or direct deduction order (except where the bank has previously provided this information). 

I believe this refers to a POA for the account holder that is receiving the benefits in question. I can't find any information about accounts that you are POA for, sorry.

As the saying goes, they can do all the checks they want on my Bank accounts, there's nowt in either of them anyway.
