                Report of Ernst & Young LLP, Independent Auditors

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

In planning and performing our audit of the financial  statements of MFS Charter
Income Trust,  (the Fund),  for the year ended  November 30, 2002, we considered
its internal control,  including control activities for safeguarding securities,
in order to determine our auditing  procedures for the purpose of expressing our
opinion on the financial  statements and to comply with the requirements of Form
N-SAR, not to provide assurance on internal control.

The  management of the Fund is  responsible  for  establishing  and  maintaining
internal control. In fulfilling this responsibility,  estimates and judgments by
management  are  required to assess the expected  benefits and related  costs of
controls.  Generally,  controls  that are  relevant  to an audit  pertain to the
entity's objective of preparing financial  statements for external purposes that
are fairly presented in conformity with accounting principles generally accepted
in the United States.  Those controls include the safeguarding of assets against
unauthorized acquisition, use, or disposition.

Because of inherent  limitations in internal  control,  error or fraud may occur
and not be detected.  Also,  projection of any evaluation of internal control to
future periods is subject to the risk that it may become  inadequate  because of
changes in conditions or that the  effectiveness of the design and operation may
deteriorate.

Our consideration of internal control would not necessarily disclose all matters
in  internal   control  that  might  be  material   weaknesses  under  standards
established  by the  American  Institute  of  Certified  Public  Accountants.  A
material weakness is a condition in which the design or operation of one or more
of the internal control components does not reduce to a relatively low level the
risk  that  misstatements  caused  by error or fraud in  amounts  that  would be
material in relation to the financial statements being audited may occur and not
be  detected  within a timely  period  by  employees  in the  normal  course  of
performing  their assigned  functions.  However,  we noted no matters  involving
internal  control  and  its  operation,   including  controls  for  safeguarding
securities  that we consider to be material  weaknesses  as defined  above as of
November 30, 2002.

This report is intended solely for the information and use of management and the
Board of Trustees of MFS Charter  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.

                            MFS Charter Income Trust

(a)(i)      Based upon their evaluation of the registrant's  disclosure controls
            and  procedures  as  conducted  within 90 days of the filing date of
            this report,  the  registrant's  chief  financial  officer and chief
            executive officer have concluded that those disclosure  controls and
            procedures   provide   reasonable   assurance   that  the   material
            information  required  to be  disclosed  by  the  registrant  in the
            reports it files or submits  under the  Securities  Exchange  Act of
            1934,  as  amended  (the  "1934  Act"),   is  recorded,   processed,
            summarized and reported in substantial  compliance with the 1934 Act
            and the Commission's rules and forms thereunder.

(ii)        There  were no  significant  changes  in the  registrant's  internal
            controls or in other factors that could  significantly  affect these
            controls subsequent to the date of their last evaluation.

         including   any   corrective   actions   with  regard  to   significant
