Analysis: BBC business editor Kamal Ahmed
It's not quite money down the back of the sofa, but the chief executive of Tesco has been hunting for bits of the business he can sell ever since arriving at the beleaguered supermarket last year.
He needed to get rid of assets to fend off speculation that the supermarket's debt - which was standing at over £20bn - was becoming a problem. The South Korean sale goes some way to alleviating the business's balance sheet strain.
Speculation was growing that without significant sell-offs Tesco might need to raise fresh capital from shareholders - never a happy prospect.
Tesco's debt now stands at £17bn, including pension liabilities, so Mr Lewis still has some way to go.
