At the Brandenburg Gate in Berlin, Russian opposition politician Olga Galkina tries to liven up a group of around 30 fellow exiles in the rain at a counter-protest against Germans calling to end military aid to Ukraine, but appears dismayed. For weeks now, various factions in Russia's fragmented and exiled opposition to President Vladimir Putin's regime have been tearing each other apart over compromising files in a war of "kompromat", or "dirt". "We are all forced to be in the same trench right now," she tells AFP. "Until the moment when we can come back to Russia and do politics there, we cannot allow ourselves to argue...all feuds have to be put aside until the moment when we return." IMAGES AND SOUNDBITES
