Pictures of David Cameron at Bushmills Distillery on the north Antrim coast:
The prime minister visited the famous site early on Saturday morning as part of his UK-wide tour campaigning for a Remain vote on the EU.
Mr Cameron toured the distillery in Co Antrim, where he was shown how barrels are sealed.
A spokeswoman for Old Bushmills Distillery said the firm was “delighted” to have hosted a visit by the prime minister.
“Old Bushmills Distillery is part of a global company, selling in global markets,” she added.
“We believe the matter of UK membership of the EU is for individual voters to decide on.”
The spokesomwan said: “Access to the EU market of 500 million people is important in a global context and will remain so.”
Later the prime minister travelled south to a dairy farm near Ahoghill.
He toured Ballybollan House and then spoke to farmers and took questions from them.
He said that the UK’s economy and farming industry were too closely linked to the EU to risk the “leap in the dark” of voting to quit the 28-nation bloc.
