Belarusian leader Alexander Lukashenko seems set on burning once “brotherly” bridges with the Kremlin during a volatile election campaign that has seen him arrest Russian citizens and raid a bank with links to Moscow. The strongman leader of ex-Soviet Belarus has accused “puppeteers” and “Telegram channels” with ties to Moscow of meddling in the August 9 elections in which he is expected to secure a sixth term. His security services stormed Belgazprombank — a subsidiary of Russian energy giant Gazprom — which was once headed by a now jailed opposition candidate, and Gazprom criticised the installation of new management. The 65-year-old authoritarian leader has also called for military exercises near the Russian border. But the biggest upset came last week when his KGB security services arrested 33 Russians, calling them mercenaries who were dispatched over the frontier to stir unrest. Belarus is more tightly linked to Russia than any other country and the two form a “union state” with an integrated economic zone, military alliance, and potential for even deeper unification.But the partnership has come under strain in recent years, and Lukashenko’s recent moves could act as a final blow that ruptures the special relationship. During a televised address to the nation this week, Lukashenko said Belarus was important to Russia because Moscow “does not have any other close allies left”. He has raised the prospect of a “point of no return, when relations between the two countries turn from brotherly and strategic into ordinary and practical,” said Arseniy Sivitski, director of the Center of Strategic and Foreign Policy Studies in Minsk.Power trip In Russia, official comments on the elections have been reserved, with Kremlin spokesperson Dmitry Peskov describing the vote as a domestic issue in Belarus.But the outspoken leader of the nationalist LDPR party Vladimir Zhirinovsky accused Lukashenko of being addicted to power after ruling over Belarus for 26 years.
