Egyptian presidential favourite Abdul Fattah al-Sisi has vowed that the banned Muslim Brotherhood group will be finished if he wins.

On national television, Egypt's presidential frontrunner Abdul Fattah al-Sisi appeared to rule out reconciliation with the Muslim Brotherhood movement.

The former army chief removed Egypt's first democratically elected President Mohammed Mursi from power last July after mass protests and launched a crackdown on Mursi's Brotherhood party.

He is widely expected to win the presidential election later this month.

"I want to say to you that it is not me who put an end to them. You, the Egyptians, put an end to them. The Egyptians said 'no'. On the 30th of June (2013) they said no, and now they are saying no. Their problem is not with me personally. The problem is with the Egyptian people. No-one, no matter how powerful he may be, can take steps that the Egyptian people do not agree with."

During the interview he was asked whether the Brotherhood would cease to exist during his presidency, Sisi answered: "Yes. That's right."

He also revealed that two assassination plots against him had been uncovered.

An Islamist militant insurgency has been growing since Mursi's overthrow. Islamist militants have killed several hundred members of the security forces in bombings and shootings.

A bomb blast in Cairo on Friday killed a policeman.

The army-backed authorities have outlawed the Brotherhood and thousands of its supporters have been arrested and hundreds killed.
