Cossacks wow the crowdsThe Ukrainian Cossacks attracted the crowds again this year with their daring display of tricks and stunts on horseback. TV chef Rosemary Shrager was among the audience. Rosemary said: "They were fantastic. I heard the music from my stand and just had to come and have a look. They are wonderful horsemen." The RWS has become a favourite of Rosemary's. She said: "The RWS and the York show are my favourite two," she said."It's lovely to see all the young farmers and meet the farmers who produce our meet. I'm doing cooking demonstrations over at the Tesco stand where we're cooking Welsh Lamb and beef as a competition for the farmers."

Hard work pays off for Kate and HuwIt's been a show day to remember for Kate Phillips and partner Huw Williams, who have scooped champion and reserve champion with their badger face Welsh Mountain Sheep named Torddu.Kate said: "It has been a lot of work leading up to the day. We've got 16 sheep in altogether this year."Huw and Kate farm with his father at their family Banc Tally, Builth Wells. Kate said "It feels pretty amazing really to have done so well. It's always an honour to come here and show at such an event. It's always amazing to go home from here with any card but to go home with a red is really special."

'It is important to remember what we must protect' Dafydd Elis-Thomas has officially opened this year's show. Lord Elis-Thomas said: "We have two royal services here today, the Royal Regiment of Wales who are a fantastic display and the RWAS who protect and promote our Welsh food. As we stand in solidarity with other nations such as France it is important to remember what we must protect."It is agricultural activity that has made Wales. Farming has shaped and re-shaped our landscape over millennia."Dafydd Jones, Wales YFC senior member of the year, said: "Back in May I attended the YFC Seminar on the EU Referendum and it was encouraging to see that so many young farmers are determined to find ways to meet the new demands that us farmers will face when departing the EU. This is a big week for Wales YFC."Richard Jones, this year's show president, said: "I am proud to preside over such a prestigious event which is Wales' shop window to the world. Like the Welsh football team, we are a small nation with a big heart."

Brexit talk 'will dominate this year's show'Stephen James, the President of NFU Cymru, said talk of Brexit would dominate this year’s show.Mr James said that significant changes were on the horizon for Welsh farmers, but emphasised that NFU Cymru has already taken part in key post-Brexit discussions in Cardiff Bay, Westminster and Brussels and that the union would continue to ensure its members’ voices were heard.Mr James said: “The Royal Welsh Show is the first time that the industry in its entirety will have gathered together to chew the fat on the referendum result. It is more important than ever that our industry uses this opportunity to highlight what we deliver to Welsh society.“The Welsh Government Well-Being of Future Generations Act is about improving the social, economic, environmental and cultural well-being of Wales. The contribution that farming makes to the achievement of all of the well-being goals is unparalleled by any other industry.“We have written to the First Minister and Cabinet Secretary to highlight the many ways in which we are achieving those goals. We have outlined that farming is the £6.1bn cornerstone of the Welsh food and drink industry and the backdrop to the £2.5bn tourism industry, showing that the Welsh agricultural industry is a key generator of wealth and employment of the people of Wales. Welsh family farms are typically linked with 40-80 other local businesses, underpinning the rural economy.“In the face of predicted challenges to our global food production in the future, Welsh farmers have a key role to play feeding the people of Wales and in contributing to current and future food security. Welsh farmers are also key promoters and protectors of Welsh culture, heritage and language, too.“Agriculture works for Wales on so many levels it is imperative that we can work together with Government and our industry partners to build a post-Brexit Welsh Agricultural Policy that ensures we are competitive on UK, EU and global markets."

Wales can be 'post-Brexit powerhouse'The Farmers’ Union of Wales says Wales has an opportunity to be a rural economic powerhouse post-Brexit.

Union president Glyn Roberts said: "In these times of political uncertainty, only a few things are constant: the grass will continue to grow and it will probably rain soon.

"So we are blessed with those strategic resources that make our industry successful.

"You may be surprised to learn that there are almost as many people engaged in the milk industry in Pembrokeshire as there are people making a living in our Welsh steel industry. Yet there is a clear imbalance in political focus for supporting these two very important industries - an imbalance which also extends to all our agricultural sectors."

Mr Roberts also called on politicians to resist the temptation to trigger Article 50 of the Lisbon Treaty prematurely for a number of reasons, not least because of the vast amount of work which needs to be undertaken to repeal, or redraft the 5,500 acts relating to agriculture and the rural economy.

Join the police for a garden party

Dyfed-Powys Police is inviting show visitors to its garden-party themed marquee and take part in The Big Conversation.

Visitors will be able to explore a police vehicle, meet a police dog, dress up as a police officer and pose for photos at an Instagram photo booth.

People will be asked a few informal questions about their experiences of the police and what they expect from officers.

To allow people to chat without distractions from the children there is a special children’s area where they can have their fingerprints taken, colour a police-themed picture and play a giant police-themed garden game.

Superintendent Robyn Mason for Powys said: "Come take the weight off your feet and join in the fun at our garden party-themed marquee. We’re providing an inviting setting for people to relax, meet police officers and specialist staff and join in the Big Conversation. WeÕll be asking people about their experiences with the police, what they expect from us and what we can be better at. There will also be ample opportunity for visitors to get valuable guidance on how to protect themselves from crime, in particular cyber-crime and scams, which are an increasing concern."

Visitors will also be able to test their knowledge of how to appropriately use the police 101 and 999 telephone numbers and get involved in keeping their communities safer by signing up to the new Dyfed Powys Community Messaging system.

There will be police experts from Financial Crime Team and Digital Communications and Cyber Crime Unit ready to carry out checks on privacy and security settings on phones, tablets and laptops at the tech Health Check zone.
