LONDON (Reuters) - Britain's Marks & Spencer (>> Marks & Spencer Group) has appointed India's Tata Consultancy Services (TCS) (>> Tata Consultancy Services Limited) as its technology partner and is targeting annual efficiency savings of about 30 million pounds ($40.5 million) in the area by 2021-22.

M&S said on Tuesday implementing a new technology programme, which involves TCS taking on core supplier services and management of specialist suppliers, would incur a one-off cost to implement of 25 million pounds.

In November the clothing and home retailer detailed a new five-year strategy, part of which involved eking out 340 million pounds of additional annual cost savings.

M&S said the technology changes will involve about 250 existing M&S roles transferring to TCS roles.

The firm will retain a small in-house technology team.

M&S is scheduled to update on Christmas trading on Thursday.
