WH Smith has secured a deal with the Post Office to open 70 Post Offices in its high street stores.

The agreement follows successful trials in six WH Smith stores and is a “natural fit” between the two companies, WH Smith said.

WH Smith this morning reported a 7% increase in pre-tax profit to £59m for the six months to 28 February, on group sales down 6% to £721m. Total like-for-like sales fell 6%.
