             Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Trustees of MFS Multimarket Income Trust

In  planning  and  performing  our  audit  of the  financial  statements  of MFS
Multimarket   Income   Trust   (the   Fund)  as  of  and  for  the  year   ended
October   31,  2008,  in   accordance   with  the standards of the Public
Company Accounting  Oversight Board (United States),  we considered  the Fund's
internal  control over  financial  reporting,  including controls  over
safeguarding  securities,  as a basis for designing our auditing
procedures for the purpose of expressing our opinion on the financial statements
and to comply with the  requirements  of Form N-SAR,  but not for the purpose of
expressing an opinion on the  effectiveness  of the Fund's internal control over
financial reporting. Accordingly, we express no such opinion.

The  management of the Fund is  responsible  for  establishing  and  maintaining
effective  internal  control  over  financial  reporting.   In  fulfilling  this
responsibility, estimates and judgments by management are required to assess the
expected  benefits and related costs of controls.  A company's  internal control
over financial  reporting is a process designed to provide reasonable  assurance
regarding  the  reliability  of  financial  reporting  and  the  preparation  of
financial statements for external purposes in accordance with generally accepted
accounting  principles.  A company's  internal control over financial  reporting
includes those policies and  procedures  that (1) pertain to the  maintenance of
records  that,  in  reasonable   detail,   accurately  and  fairly  reflect  the
transactions  and  dispositions  of the  assets  of  the  company;  (2)  provide
reasonable  assurance  that  transactions  are  recorded as  necessary to permit
preparation  of financial  statements  in  accordance  with  generally  accepted
accounting  principles,  and that receipts and  expenditures  of the company are
being made only in accordance with authorizations of management and directors of
the company; and (3) provide reasonable assurance regarding prevention or timely
detection of unauthorized acquisition,  use or disposition of a company's assets
that could have a material effect on the financial statements.

Because of its inherent  limitations,  internal control over financial reporting
may not prevent or detect misstatements.  Also, projections of any evaluation of
effectiveness to future periods are subject to the risk that controls may become
inadequate  because of changes in  conditions,  or that the degree of compliance
with the policies or procedures may deteriorate.

A deficiency in internal control over financial reporting exists when the design
or operation of a control does not allow management or employees,  in the normal
course  of  performing   their   assigned   functions,   to  prevent  or  detect
misstatements  on a timely  basis.  A material  weakness is a  deficiency,  or a
combination of deficiencies,  in internal control over financial reporting, such
that  there is a  reasonable  possibility  that a material  misstatement  of the
company's  annual or  interim  financial  statements  will not be  prevented  or
detected on a timely basis.

Our  consideration of the Fund's internal  control over financial  reporting was
for  the  limited  purpose  described  in the  first  paragraph  and  would  not
necessarily disclose all deficiencies in internal control that might be material
weaknesses  under  standards   established  by  the  Public  Company  Accounting
Oversight  Board  (United   States).  However,  we  noted  no
deficiencies  in the Fund's  internal  control over financial  reporting and its
operation,  including controls over safeguarding securities, that we consider to
be     a     material      weakness      as     defined      above     as     of
October 31, 2008.

This report is intended solely for the information and use of management and the
Board of  Trustees  of MFS  Multimarket  Income  Trust  and the  Securities  and
Exchange  Commission  and is not intended to be and should not be used by anyone
other than these specified parties.
