Government statistics show that Poland's economic growth likely slowed to 2 percent in 2012, down from 4.3 percent the year before, underlying concerns that one of Europe's fastest growing economies has fallen victim to the region's economic troubles.

The figure, a preliminary estimate published Tuesday by the Central Statistical Office, was in line with the expectations of many economists.

A key reason for the slowdown is a slump in domestic demand as household spending has fallen to what appears to be its slowest rate since the early 1990s, according to London-based Capital Economics.
