Prime Minister Rishi Sunak and First Minister of Wales Mark Drakeford haven't spoken since March. Mr Sunak's predecessors Liz Truss and Boris Johnson had both been pretty clear in their disdain for devolution.
Mr Johnson called devolution a disaster whereas Ms Truss said that the best way to handle then Scottish First Minister Nicola Sturgeon was to "ignore her". In both cases this disdain manifested itself in them refusing to speak to First Minister Mark Drakeford for months at a time. In the case of Liz Truss this was her entire tenure.
When Mr Sunak took over he expressed a desire for a better working relationship between the UK and Welsh Governments and called the First Minister, as is tradition, within 24 hours of taking office. However this does not mean that there has been regular direct contact between the pair since then.
