It may just be lunch, but a change to Sainsbury's kosher sandwich options has caused uproar among some Jewish customers.

The supermarket chain has reduced the number of kosher sandwiches available in its popular "meal deal" range from four to one.

Shoppers have been left with only the sliced-egg version under the offer, which includes a drink and an additional snack for a total of £3.

At the same time, the supermarket has reduced the prices on the three kosher sandwiches no longer in the meal deal. They now cost from £2.20.

The price cut has not appeased kosher meal deal fans.

Rabbi Alex Chapper, of Ilford Federation Synagogue, said: "The availability of kosher sandwiches for Jewish people is important, so it's a shame. I'd encourage them to change their minds."

Customer Oliver Sonenfield said he was disappointed. "The meal deal was a kosher, convenient, inexpensive lunch," he said.

One member of the community, who did not want to be named, said the move "completely alienates a whole section of the community who can only eat those sandwiches".

Others claimed Jewish customers were being discriminated against.

One tweeted that it was an example of "institutional antisemitism par excellence".

Sandwiches in other, non-kosher, ranges, have also been removed from the meal deal offer.

A spokeswoman for the supermarket said the changes were "in line with our strategy to phase out multibuys across the store in favour of simpler, everyday prices".

She added: "We can reassure customers that if their favourite lunch item is no longer part of the deal, they can still expect great value with a lower, regular price." She declined to comment on claims of discrimination.
