New UK Prime Minister, Boris Johnson will meet Welsh farmers and workers to talk Brexit on his first visit to Wales on Tuesday.
The farming sector employs more than 50,000 people in Wales, while the food and drink sector is Wales' largest - contributing almost £1.7bn to its economy.
Mr Johnson is expected to tell farmers and food producers they will continue to thrive in post-Brexit Britain.
The new Prime Minister insisted the UK will leave the EU with or without a deal on October 31, but 'no-deal' was not the country's default position.
Mr Johnson will also meet First Minister Mark Drakeford to update him on his government's approach to Brexit negotiations.
Ahead of the meeting, Mr Drakeford said the UK Government must work with the Welsh government to "mitigate negative effects on Wales and its economy.”
In a later tweet, Mr Drakeford also said a no-deal Brexit would be ''catastrophic'' for Wales.
During a visit to Scotland on Monday, Boris Johnson said he still believes a deal with the EU can be done.
