Russian tradition orders that men should kiss each other three times on the cheeks at official functions. Now, a new ruling in Moscow is calling for politicians in the capital to stick to the old handshake. According to Britain's The Telegraph newspaper, politicians in Moscow have been told to stop kissing each other when they meet because the “kissing ceremony” takes so long.

Leonid Brezhnev, the general secretary of the Communist Party from 1964 to 1982, was famous for treating male colleagues to a full lip-lock. One photograph of him kissing Erich Honecker, the leader of the Democratic Republic of Germany, was used for a protest painting on the Berlin Wall with the caption: "Oh, God, help me survive this deadly love".

Kissing three times on the cheeks at official occasions is a Russian tradition. The practice has been revived among high-ranking officials in past years. In the distant past, a kiss from the tsar (emperor) was the highest sign of recognition. The Moscow ruling, however, has prompted authorities in other cities to consider banning the practice.

Alexei Kleshko, a parliament member in Siberia, said: “Single-sex kisses should be avoided, including at official meetings. It's enough to shake hands. Of course, if one is talking about a long friendship or fatherly relations, it might be OK to embrace. But that's the maximum that should be allowed.”

Another MP Vladimir Gorlov, said he only allowed himself to kiss the hand of a woman at work: "There are informal relations and there are meetings governed by protocol," he said. “When a man is kissing another man at an official event, I have a negative attitude towards it. There are rules of decency. "
