Francis Boulle thinks Louise Thompson should dump Spencer Matthews for good.

The 'Made in Chelsea' star has slammed his co-star for cheating on the brunette beauty last year, and he thinks "weak" Louise should leave her on/off boyfriend forever if she has any "self respect".

He said: "If one of my friends has been cheating on their girlfriend, it's none of my business, but I say it's probably your responsibility to tell them if you want to continue to be in a relationship with them. There's no point if people are being deceived and it's just a lie - I don't like liars.

"I think he can manipulate her, but maybe she's a bit weak. At the end of the day, I think that if she still has some level of self respect, she will move on."

The entrepreneur also feels the 24-year-old lothario has some "growing up" to do following their vicious argument in the latest series of hit E4 reality show.

He added to Star magazine: "Obviously everyone has their own flaws to work on, so I think he's got some growing up to do in some areas. You know, he thinks he can get away with things when he shouldn't. I just think people need to learn."
