Every year, Moscow wraps itself in patriotic pageantry for Victory Day, a celebration of its victory over Nazi Germany in the Second World War.

Today marks the 79th anniversary and Mr Putin addressed the parade in the Red Square, trying to talk up his country's military capabilities in a speech aimed as much at the foreign audience as a domestic one.

During this year's speech, Mr Putin admitted that Russia was going through a "difficult period" as the "future of the motherland depends on us".

"Today on Victory Day we are conscious of that even more acutely," he said before warning: "Our strategic forces are always combat ready."

The leader of the Kremlin also said Russia's nuclear forces were always at combat readiness, as he addressed massed ranks of Russian servicemen.

Mr Putin said on Thursday that Russia would do everything it could to avoid global confrontation, but it would not allow anyone to threaten it.

He also used the speech to send a message to the Russian troops fighting in Ukraine, trying to bolster their morale as the war continues to drag on.

He finished on: "Glory to the armed forces, to Russia, to victory."

Since coming to power on the last day of 1999, Mr Putin has made 9 May an important part of his political agenda, featuring displays of military might.

Columns of tanks and missiles roll across Red Square and squadrons of fighter jets roar overhead as medal-bedecked veterans join him to review the parade.

Many wear the black-and-orange St. George's ribbon that is traditionally associated with Victory Day.
