Department store chain BHS said it will make more than 350 people redundant and may close dozens of stores in a step to revive its ailing business.

The under-pressure retailer is cutting 150 staff from its head office and 220 from its shops, while more jobs could be lost if it decides to roll out store closures.

It comes after BHS warned that dozens of its stores could be shut unless landlords slash the rents on more than half its UK shops.

The fashion and homewares retailer - which has 164 shops - has pinpointed 47 stores which could continue to trade if monthly rents were cut by 50% or 75%.

It said another 40 stores may close after 10 months unless landlords agree to cut the rents "substantially".

However, the retailer said it would pay the rent at the current rate at 77 of its "most viable" stores, but would now make monthly rather than quarterly payments for the next three years.

The move to drive down the costs of its rental bill is part of proposals outlined in a company voluntary arrangement (CVA), as its owners attempt to restructure the loss-making chain.

Struggling companies try to agree a CVA with creditors in order to turn their business around while paying off debts. Creditors will vote on BHS' CVA on March 23.

Will Wright, restructuring partner at KPMG and proposed "supervisor" of the CVA, said: "For almost 90 years, BHS has been one of the most iconic brands on the UK high street, but in recent years has seen its profitability decline as it has sought to respond to changing customer behaviours, increased competition and the rise in omni-channel retailing."

He added: "The CVA proposals are one facet of a wider turnaround plan, and specifically tackle one of the business' largest fixed costs, the onerous lease arrangements across its UK-wide store portfolio."

The retailer said it hoped to keep store closures to a minimum.

BHS was sold by billionaire retail tycoon Sir Philip Green for £1 to Retail Acquisitions in March last year, as losses widened to £21 million in 2013-14, up from £19.3 million the year before.
