Welsh Conservative MPs have written to the First Minister expressing concern over the lack of access to food supplies experienced by vulnerable people during the coronavirus crisis.
More than 80,000 'extremely vulnerable' people in Wales received letters from NHS Wales asking them to undertake shielding measures.
On Wednesday, Health Minister Vaughan Gething said ministers, supermarkets and wholesale suppliers were in talks to give priority access to shielded people.
But 12 MPs told Mark Drakeford constituents are still struggling to access food supplies through online supermarket deliveries.
Around 1.5 million people in England were also identified as highly vulnerable and warned to stay at home for 12 weeks.
Welsh MPs have argued that "the version received by individuals across the border facilitates priority access to supermarkets."
They added: "These policy areas are devolved to the Welsh Government, so it would be helpful if you were able to advise why this provision was not included here in Wales."
The Welsh Government has promised to provide support to those shielding who cannot get help from family members, friends or neighbours.
The first of weekly food boxes were delivered on Friday, containing enough essential foods in packages and tins for one person who is shielding for one week.
The Welsh Government said it is working with supermarkets to find a ''simpler and secure'' scheme to provide priority deliveries for those people who have received a letter from the Chief Medical Officer asking them to adopt shielding measures for 12 weeks.
