BUDAPEST, Jan 21 - Hungarian Prime Minister Viktor Orban's government announced on Wednesday a 100 billion forint ($304.42 million) package to shore up the restaurant industry as the veteran leader faces an uphill battle to revive the economy ahead of an April election.

Orban, whose right-wing Fidesz trails opposition challenger Tisza based on most fresh surveys, has also flagged a possible extension of energy price subsidies to help Hungarians cope with rising heating bills amid freezing temperatures.
