Clematis disease


Just returned from a week's holiday to find this has happened to my spring flowering clematis. It's about 7 years old. Should I cut off the affected branches which is most of it?  Tried treating with an insecticide but to no avail. Help and advice would be much appreciated. 

Thanks in advance.

    Not sure which Clematis this is, but it looks like more than one problem. I do agree that it's best to just cut them all off if it is a spring growing variety. Sounds like you have tried to treat a problem. What was the issue originally? Most Clematis plants need rich and slightly moist soil. Planting position may not be right for it, hence it is weak and susceptible to attacks. Is it too dry? I must admit, the photos look like they're completely dried out. The stems look dead already. Growing too near large shrubs/trees or too near the wall of a tall building. 

    Not sure with the first picture, it looks like a deformed leaf? Are they different types of Clematis you are having problems with?
