Russia has opened a murder investigation after a journalist, Darya Dugina, died in a suspected car bombing not far from Moscow. Was she the target? Or was it her father, the ultra-nationalist philosopher Alexander Dugin?

Victoria, Vitaly and Gabriel Gatehouse, who interviewed Alexander after the annexation of Crimea, profile the man said to be one of Putin’s inspirations.

They also talk about who might be behind the murder and what consequences there might be in Ukraine, where Independence Day celebrations planned for Wednesday have already been curtailed.
