James Duddridge MP has written to the Chief Executive of Marks and Spencer to seek reassurances over the future of M&S in Southend High Street.
The Member of Parliament for Rochford and Southend East stressed that the retailer was an important local employer and played a key role in the High Street.
Last week it was announced that 30 Marks and Spencer stores will close over the next 10 years.
"If Southend's Marks and Spencer were to close it would be another big loss to our High Street.
"I have therefore written to the Chief Executive of M&S to seek reassurances that our store is not earmarked for closure.
"I will, of course, keep residents updated in due course."
