Two main Egyptian opposition parties, namely El Wafd and El Tagammu, have decided on Friday to join the dialogue with the new government called upon by Vice President Omar Suleiman, state TV reported.

The two parties agreed to join the dialogue after the government responded to their demands to protect the demonstrators in Tahrir square and investigate into the criminal perpetrators.

Both Suleiman and Prime Minister Ahmed Shafiq said Thursday the government had started dialogue with the opposition parties and representatives of the protesters.

Egyptian President Hosni Mubarak announced on Tuesday he wouldn 't run for the next presidential elections and ordered constitutional reforms, inviting the political parties for talks on economic and political reforms after massive anti-government demonstration hit the country and left dozens killed and hundreds injured.

Almost all the legal political parties have agreed to take part in the dialogue, which was still rejected by the banned Muslim Brotherhood, Egypt's largest opposition group, and top dissident ElBaradai, who asked for an immediate departure of Mubarak before they accept any dialogue.

Tagammu Party Leader Refaat al-Said said on Friday that apart from constitutional and political reform, the parties will ask for a minimum wage limit and the formation of a judicial committee on the security vacuum and the breakaway of prisoners during the protests, official MENA news agency reported.
