  Cosmological observations on the largest scales exhibit a solid record of
unexpected anomalies and alignments, apparently pointing towards a large scale
violation of statistical isotropy. These include a variety of CMB measurements,
as well as alignments of quasar polarisation vectors. In this paper we explore
the possibility that several of the aforementioned large scale correlations are
in fact not independent, and can be understood in a coherent way within the
framework of a parity odd local Universe, and ultimately related to the nature
of Dark Energy and its interactions with light.
