From 2007 to 2017, the Telegraph was actually one of four European newspapers that published Russia Beyond The Headlines (a project from Russia's state news outlet) as a supplement.
The Telegraph Group has recently been in financial trouble and bailed out by a company run by the vice-president of the UAE Mansour bin Zayed Al Nahyan. While Putin is visiting the UAE next week, Mansour is probably best known in the UK as owner of top-flight football team Manchester City, so him doing stuff in the UK is not anything new. On the other hand there is a government probe in to this acquisition, perhaps unsurprising considering that the Telegraph is one of the four newspapers of record in the UK despite how shit it is
