This has been discussed before. There is no anti-competition law that could have been used to assess whether or not the transaction should proceed.
I do not know if there was such legislation, whether it would have prevented the transaction. I do not know, for sure, whether the transaction would have been refused if it took place in the UK.
Even if there was the legislation and the transaction was deemed to fall within it and refused, what would happen next?
Empty Shoprite stores across the island? Several independents taking on some of the stores? Aldi or Lidl stepping in?
The fact is it has happened. No doubt Tesco are monitoring performance of all stores and will probably make adjustments to maximise the performance of each.
As we keep on saying, it all has to settle so we know exactly what we have.
