Reclaim money from EU State for EU citizen Claiming benefits

Dear Sir or Madam,

Can you tell me how much money has the British Government has
claimed back from the EU States for Benefits paid to EU citizen in
the last 10 years, if you don't hold this information it will be
from when the information has been recorded.
Can you also tell me how much money the British Government has
failed to claim back for benefits paid in the last 10 years. Again
if you don't hold this information then if from when you are able
to gather this information.
I am deeply concerned that you don't seem to have any information
or statistics on previous FOI I and other have request of a
financial nature. Regarding State benefits. You should be acting
these non answered quesion, as held data requests is vital for the
UK economy and British tax payers. It is also seen a bad money
management for Public funds or in another case the Government is
trying to hide something from the public

Yours
Ann Brown

Yours faithfully,
