ROME- Italian Prime Minister Silvio Berlusconi says he is ready to return to work on Monday after spending four weeks recovering from an attack that broke his nose.

Berlusconi, 73, has been convalescing first in hospital and then in the south of France and at his Milan villa since a man with a history of mental illness hurled a statuette at him at a rally on Dec. 13.

I'm better now, I still have a little mark on my face, you can still see it, they tell me it will go away but unfortunately I've lost a tooth, Berlusconi, who has had a face lift and hair transplant in recent years, said in a newspaper interview.

From Monday I will be back at (the official Rome residence) Palazzo Chigi working on all fronts, the media mogul told Repubblica daily, listing priorities as tax reform and overhauls of the legal system and of Italy's constitution.

Berlusconi said he was working with Economy Minister Giulio Tremonti to eventually implement just two income tax rates, of 23 percent and 33 percent, instead of the current five main rates ranging from 23 percent to 43 percent.

This costly reform was first pledged by Berlusconi when he entered politics in 1994.
