The disqualified winner of last year's presidential election in Georgia's breakaway region of South Ossetia has officially registered her new political party.

The new party of Alla Dzhioyeva, a surprise winner over a Kremlin-backed candidate in the November 2011 election, is called Ossetia -- Liberty Square.

Dzhioyeva made headlines last year after supporters rallied against a Supreme Court decision to invalidate the presidential election in which preliminary polls showed Dzhioyeva was winning.

Dzhioyeva was barred from taking part in the repeat presidential poll in April and Kremlin-backed Leonid Tibilov was announced the winner.

South Ossetia broke away from Georgia in the early 1990s.

Russia recognized it as an independent state following a brief war with Georgia in 2008, something only five other countries have also since done.
