A defiant Mubarak addressed the people of Egypt tonight, saying he will continue to remain president until presidential elections in September, but would delegate presidential responsibilities to newly appointed vice-president Omar Sulieman.

Protesters at Tahrir Square in downtown Cairo, who numbered around 3 million, broke in chants calling for the overthrow of Mubarak, while the speech was going.

As soon as the speech was over, the chants rose, against both Mubarak and Sulieman, clearly showing that the crowds rejected the speech. Among the chants was: “We're off to the palace (presidential), we're going as millions of martyrs.”

Here's a round up of some of the reactions from Twitter, as soon as Mubarak ended his speech:

@tololy: Mubarak delegats presidential responsibilities to VP Omar Suleiman #Egypt #Jan25

@algergawi: Fact that the old man said he's staying till “September” at this speech is proof he put the S in stubborn. #Jan25

@asadabukhalil: This speech will go down in history as the dumbest speech ever delivered by a dictator.

@LabibaLaith:

@Egyptocracy: #Mubarak referred to himself in the 3rd person again. He did that already in his last speech. #Egypt #Jan25 #Tahrir

@hazemzohny: Expect utter governmental collapse. The army and NDP Sec. General just said good news coming. This speech is the opposite #Jan25 #Egypt

@fasi_zaka: Mubarak to stay interning in Egypt. Starts Grad school in September. #Hosni #mubarak #jan25 #egypt

@twilight2000: State TV suddenly NOT showing the crowds in #Tahrir – no surprise – only AJE is showing them now. ~AJE #jan25

Millions will be marching across Egypt tomorrow, Friday, and estimates say crowds will swell to more than 20 million.
