The UK government and the Scottish National Party (SNP) are set to clash over the introduction of a deposit return scheme (DRS) in Scotland.

The Scottish government intends to press ahead with plans to introduce a 20p deposit on cans and bottles from 16 August.

Consumers would then be able to reclaim that deposit by recycling them.

For it to work properly, the SNP would need an exemption from UK wide rules that prevent different regulations applying on products in Scotland and the rest of the UK.

The Guardian reported that the exemption request will be rejected in the latest clash between Westminster and Holyrood.

A spokesperson for the Scottish government said: “We expect a decision from the UK government as soon as possible given that this is what is needed to give industry absolute clarity.”

Scotland secretary Alister Jack has criticised the plans as ‘badly designed and inflationary’.

The rest of the UK is planning its own deposit return scheme, but that is not set to be implement for another two years.
