John Lewis is said to be close to agreeing a deal to open its fourth department store in London at an extension of the Westfield shopping centre.

According to the Daily Telegraph, the retailer is said to be keen to open at the west London site but a final decision will be taken at a board meeting for the John Lewis Partnership scheduled for next month.

Westfield are reported to have drawn up ambitious plans to extend its shopping centre in Shepherd‘s Bush, which opened in 2008. It has outlined planning permission for work to begin on a £1bn scheme next to the existing centre that includes 550,000 sq ft of retail, led by a department store, along with 1,500 homes, restaurants and offices.

The new John Lewis outlet would provide competition to Marks & Spencer, Debenhams and House of Fraser which already have stores at the Westfield centre.
