Abstract
The complement M of a complex line arrangement 풜 in ℙ2(ℂ) is formal, and admits a finite cover F → M, where F is the associated global Milnor fibre. An example where F is not formal (not even 1-formal), is given in this article, using the relationship between characteristic varieties of rank one local systems and resonance varieties.
