AlQa'dah 12, 1433, Sep 28, 2012, SPA -- The French government will unveil its toughest budget in 30 years Friday, aimed at plugging a 30-billion-euro (38-billion-dollar) shortfall in the country's finances for 2013, dpa reported. President Francois Hollande has said the hole will be plugged by 20 billion euros in tax hikes divided 50/50 between wealthy households and businesses and a spending freeze that will save a further 10 billion euros. The tax hikes include a controversial 75-per-cent tax on annual incomes of over 1 million euros. The budget, which is Hollande's first, aims to cut France's budget deficit from 4.5 per cent of gross domestic product this year to 3 per cent in 2013. It is based on a growth forecast of 0.8 per cent.
