“Here we are a month after the referendum and still many constituencies in Northern Ireland are bedecked with Leave posters,” he said.
“Those who led the Leave campaign wasted no time in disappearing off and leaving others to clean up the mess they had helped create. They appear to be doing exactly the same with their posters – hoping they stay there until someone else comes along and clears them.
“Only a few hours after the EU referendum result, the Leave campaign washed its hands of its outrageously incorrect claim we send the EU £350 million a week and we should give it to the NHS instead. But those lies still remain on the many posters that continue to populate Northern Ireland.
“While Leave campaigners may have abandoned their ridiculous claims, they can’t wash their hands of their responsibilities and I call on them to bring down the rest of their posters immediately.”
