North Korea describes Donald Trump's 'bigger nuclear button' Twitter claim as 'spasm of lunatic'

North Korea has described Donald Trump’s claim that he has a “bigger nuclear button” than Kim Jong- un as the “spasm of lunatic”.

The latest instalment of the war of words between the two nations comes after the US President tweeted: “I too have a Nuclear Button, but it is a much bigger & more powerful one than his, and my Button works!”

In a commentary published on Tuesday, North Korea’s ruling party newspaper Rodong Sinmun reportedly hit back at Mr Trump, describing his comments as the “spasm of lunatic”.

The fiery exchange is not the first between the US President and his opposite number.

Mr Trump has previously described the North Korean leader as a “maniac” and “little rocket man”, while Kim Jong-un has dubbed the president a “mentally deranged US dotard” and a “gangster”.

His comments came as he said Labour’s attempts to stop Mr Trump visiting Britain were “extremely odd”, insisting the US president would visit “in due course”.

Mr Trump has cancelled a proposed visit to open the new US embassy in London, claiming the move to a new building represented a “bad deal”.

However, reports have suggested he called off his trip because he felt he had “not been shown enough love” by the British Government.
