Government plans for a "buy British button" on supermarket websites will be revealed by the environment secretary, Steve Barclay, at the Oxford Farming Conference.

There are also plans for food labelling to say when imported goods do not meet UK welfare standards.

Consistent labelling for food that adheres to the highest standards is also envisaged.

The aim is to give purchasers more details at the point of sale, with a potential consultation on clearer food labelling, such as indicating when overseas products fall short of UK welfare standards.

The recently appointed cabinet minister will also disclose major alterations to the UK’s farming support schemes, marking the largest revamp since the UK's departure from the EU.

Mr Barclay said: "British farmers take pride in producing food that meets, and often exceeds, our world-leading animal welfare and environmental standards.

"British consumers want to buy this top-quality food, but too often products produced to lower standards overseas aren’t clearly labelled to differentiate them.

"This is why I am proud to announce that we will consult on clearer food labelling so we can tackle the unfairness created by misleading labelling and protect farmers and consumers."

The planned changes to farming support schemes include compensating farmers for maintaining and improving footpaths, cycle paths and bridleways on their farms.

The government will confirm that funding will continue for items such as maps, way markers and fencing to establish access.

Both the Conservatives and Labour have dismissed the idea of introducing a Scottish-style right-to-roam law, favouring "responsible access" instead.

The Government aims to increase the number of people accessing the countryside and exploring green space, believing it can boost mental and physical health, although it insists on using designated routes.

Efforts are also in place to encourage younger generations to acquire knowledge about farming, forestry, food production and wildlife.

The Educational Access scheme is set to see an expansion.

Richard Benwell, chief executive of Wildlife and Countryside Link, said: "Reforms to enable consumers to reward farmers who stick to high animal welfare standards make sense for everyone.

"With over 200 million farmed animals in the UK, this policy is a win for farmers and for the public.

"By labelling animal food products to present information about the welfare of the animals involved, consumers can reward high welfare farmers.

"After a two-year delay to the progression of these popular and cost-effective changes, we now need to see swift progress to allow consumer choice to drive widespread improvements in the welfare of farmed animals."
