Boris Johnson did not receive a warm welcome as he arrived in Cardiff for a visit with the Welsh First Minister Mark Drakeford.
The new PM was booed as he arrived in the Welsh capital.
It follows a similar reception in Scotland where Mr Johnson was greeted with shouts of 'lying a***hole'.
He was later booed as he arrived for a meeting with First Minister Nicola Sturgeon at Bute House in Edinburgh.
The PM was today attempting to reassure the Welsh government about his plans for Brexit.
Mr Johnson says the UK will be leaving on 31st October, but today he insisted that it was the EU's "call" whether or not they wanted a deal.
He said: "We're not aiming for a no-deal Brexit and we don't think that's where we'll end up.
"This is very much up to our friends and partners across the channel. We cannot go on with the withdrawal agreement as it currently is, everybody understand that, it's dead.
"If the EU understands that I think we're going to be at the races. If they can't compromise then clearly we have to get ready for a no-deal exit."
Ahead of meeting with Mr Johnson Welsh first minister Mark Drakeford said a no-deal Brexit would endanger not only agriculture but rural life as a whole.
And he said he takes the threat of civil unrest seriously if farmers' livelihoods were at risk.
He told the Guardian during the PM's visit: “It is a sector of the economy that has the capacity, if it feels sufficiently provoked, to carry out acts of civil disobedience.”
Mr Johnson promised help for farmers facing a "tricky" situation if a no-deal Brexit results in tariffs pricing them out of EU markets.
During a tour of a poultry farm near Newport he said: "We'll make sure (the farming sector) have the support they need. If their markets are going to be tricky, then we will help them to find new markets. We have interventions that are aimed to support their incomes."
The farm's owner, Victoria Shervington-Jones, said Mr Johnson told her "it's all going to be OK" when she brought up how a no-deal Brexit could affect her business.
She said: "I told him quite a lot about our business and what we do and talked a little bit about how Brexit would effect eggs and egg products such as liquids and powder coming in from the likes of Ukraine and the USA, how that would be a really bad idea, and obviously that would happen with a no-deal Brexit because the welfare standards out in other countries are nowhere near as good as ours.
"He seems pretty confident that whatever happens it's all going to be OK, apparently. That's what he said. I didn't get a chance to ask him to clarify that but that's what he said."
John Davies, president of the National Farmer's Union Cymru, said farmers would need to see greater detail of the support Mr Johnson promised them.
He said: "We want three things. Full reciprocal tariffs across all sectors. We want them to assure that food coming in is priced to same environmental standards, animal welfare standards, and antibiotic level.
"Thirdly, public procurement. The Government buys a great deal of food for health service military, prison service. Buy British, take back control."
Meanwhile the Welsh media have complained that the Prime Minister was dodging scrutiny when he visited the country for not taking questions on camera.
ITV Wales political editor Adrian Masters said that he had refused to ask Boris Johnson a question because he was not allowed to film the exchange.
“For the record then: on the Prime Minister’s first visit to Wales the national news outlets of Wales ITV Wales, BBC Wales and WalesOnline weren’t allowed interviews,” he said. “We were offered chance to ask questions but not to film them.
“Also for the record, I refused this offer. I hate to have turned down the chance to challenge Boris Johnson but I wouldn’t have been able to broadcast any of it. I’d have had to read quotes to the audience tonight.
“I do think it’s a strange way to begin for a new Prime Minister who says he wants to strengthen the union to treat the main national news outlets this way.”
