Britain's biggest supermarket has announced a huge shake up of its UK store count in a move that could put 4,500 jobs at risk.
In a market announcement on Wednesday, the retailer said CEO Dave Lewis will step down, adding his "turnaround is complete".
However, before his departure, more changes are likely to hit Britain's troubled high streets - with convenience stores on the line.
The grocer said it now plans to open 150 more Express stores over the next three years - and four new superstores in the UK Ireland.
But added the transformation will also include 'repurposing' 153 Metro stores - with new counters in 692 stores next year. This will include reworking stores and changing roles to adapt to customer needs.
These changes are on going - having been announced in August - and will include a reduction in opening hours during quieter trading periods at the start and end of the day, and simplifying stock routines.
By February 2020, three more Jack’s stores will also open in the UK.
This is despite having already closed one branch - in Rawtenstall, East Lancashire - within a year of opening.
Last week, the chain said the branch will be replaced with a 40,000sq ft Tesco store instead, in response to demand from customers.
In Wednesday's statement, Tesco also spoke of plans to introduce a new Clubcard Plus by the end of 2019.
Meanwhile, Ken Murphy, current boss of Walgreen Boots Alliance, will replace Dave Lewis by summer 2020.
“Despite challenging external conditions we have delivered a very good start to the year. I’m very pleased to say that we have now delivered every element of the turnaround plan and from this position of strength, the transformation of our business continues at pace," Lewis said.
"The Capital Markets Day in June laid out many opportunities for further, profitable growth and I’m delighted to share today the plans to step up our store opening programme, to increase our online capacity, the introduction of Clubcard Plus in the UK and the acquisition of Best Food Logistics as the next step in our Booker growth strategy.
"With the turnaround complete and as we begin to implement the next steps of our sustainable growth strategy, now is the right time to plan a smooth and orderly succession. As such, I will step down as Group CEO next summer and pass the baton to Ken Murphy."
On Wednesday, the grocer revealed a half year profit £1.4 billion - up 25.4% - following £1.6billion in cost-saving measures.
Mirror Money has contacted Tesco for a comment on the stores affected.
The changes come less than a week after Sainsbury's announced plans to close more than 100 stores across its portfolio - but open even more as it continues its "estate review and growth plans".
The grocer said it expects to close up to 15 main supermarkets, 40 convenience stores such as Sainsbury's Locals and 70 Argos branches.
To counteract that, it's opening 10 new supermarkets, 110 new convenience stores and putting 80 Argos branches in other Sainsbury's.
"We expect the closures to deliver an ongoing net operating profit benefit of £20million per year," Sainsbury's said in an update to shareholders.
Sainsbury's told Mirror Money that there were no jobs set to go as a result of the Argos stores closing, adding that there are already 289 Argos branches inside Sainsbury's and about half of these are "redeployments".
