The opening of the new store, which has created ten jobs, is the latest development at M&S Liberty Wharf, which introduced seven-day shopping and a new Home store earlier this year.
Stephen Forrester, managing director of Marks & Spencer, said: ‘We’re delighted how well the new Foodhall sits within our Liberty Wharf complex.
‘It’s a significant investment which has created ten new job roles and I know will provide a useful facility to nearby residents and workers newly located to the Waterfront area.
‘St Helier customers will also now be able to conveniently shop for their favourite M&S food and drink on Sundays as well as the rest of the week.’
