Cairo: Public sector workers in Egypt will get a salary increase of at least 20 per cent this year, Prime Minister Ahmed Nazif said on Thursday.

It will be more than the 15 per cent earlier planned and will "not be less than 20 per cent", Nazif told state newspaper Al Messa.

The prime minister gave no further details of where the government would find the extra money.

Finance Minister Youssef Boutros-Ghali said this week that the government was considering a higher raise, but that the increase should not push up the budget deficit.

Egypt has seen a wave of worker unrest over the past year, starting with riots in the Nile Delta town of Mahalla Al Kubra on April 6 where three people were killed and more than 150 injured.
