Brexiteer Jacob Rees-Mogg has hit back at Bertie Ahern's claim that he didn't know what the Irish border was.
The former Taoiseach had described the Tory MP as a "strange fish" and a "lovely fella when he’s asleep".
Ahern also claimed that Rees-Mogg had told him that he had "no idea" what the Irish border was.
He said: "When he’s awake, he (Rees-Mogg) definitely is a strange fish I tell you, in and out of the water.

Brexiteer Jacob Rees-Mogg told Bertie Ahern he'd 'no idea what Irish border was'
"But the reality is he admitted to me he had no idea of what the border was.
"I think a lot of British politicians thought the border was something up around Dundalk or Newry, and that there was a gate on it.
"I mean the idea that it was 460 kilometres across the island and that you could criss cross it to farms and houses, they just didn’t know it.

"And regards to the fact that lot of these guys went to Oxford, Cambridge and Eton, they’re not very bright. This is the problem. There is nothing wrong with the backstop."
However the English politician has hit back at the former Fianna Fail leader's comments which he described as “quite funny but regrettably untrue”.
In a reference to the recent election of funnyman Volodymyr Zelensky, he wrote on Twitter: “Perhaps Ireland had a comedian as its leader before Ukraine.”
