Post Office CIO Lesley Sewell will leave the organisation in November 2015, with an interim CIO put in place while a permanent successor is recruited.
According to a source, she is moving to a CIO role elsewhere, but the Post Office would not comment on this.
Sewell joined the Post Office in 2010 from Northern Rock, where she had been managing director for IT since 2005. She is responsible for the development and delivery of the organisation's IT strategy, in support of its business transformation plans. She will leave after four years in the role.
The Post Office said it is “very sorry” Sewell decided earlier in 2015 to leave the business.
“Lesley has made an outstanding contribution to the company, particularly in managing the separation from Royal Mail, but also with exceptional work developing and delivering the IT strategy that supports the Post Office’s transformation, as it continues to modernise its network of 11,500 branches,” it said.
The Post Office also confirmed it has appointed an interim CIO: “While her permanent successor is appointed, Lesley is working with Post Office’s interim CIO Chris Broe, previously CIO at Rentokil and Unilever.”
The Post Office is currently going through a transformation of its IT, costing hundreds of millions of pounds.
The company recently said: “As part of our wider transformation programme, we are developing our IT and telecoms services and systems across our business, to grow and develop our business to ensure we meet our customers' changing needs.” Part of this has seen IBM named as the IT supplier for the front-office component of the transformation.
