Should Bolton resign?

UKIP leader Henry Bolton's girlfriend Jo Marney went on a racist rant about Meghan Markle, prince Harry's fiance.

Bolton has been accused of racism and xenophobia in the past, though nothing as overt as this.

Leaders of the party are calling for his resignation, due to poor judgement and racist influences. Do you think he should resign based on views his girlfriend holds, and expresses to him?

Here are the texts:

Personally, I think he should resign. This shows clear racist influences and extremely poor judgement on his part, and is a confirmation of suggestions of xenophobia and racism on his part.

What do y'all think?
