Motions supporting the Irish people's right to use force against the British, saluting the Continuity IRA which shot dead a policeman in Lurgan this year, and praising Northern rioters, are expected to be endorsed at the Republican Sinn Féin ard fheis this weekend.

Party members from both sides of the border, meeting in Dublin, will today elect a new president to succeed Ruairí Ó Brádaigh, who has led Republican Sinn Féin since 1986.

In his address, Ó Brádaigh will tell delegates: "Hard realities must be faced. There won't be peace in Ireland until British occupation ends."

He is stepping down for health and age reasons. Delegates will choose either Limerick's Des Long or Des Dalton from Co Kildare as his successor.

Security sources regard Republican Sinn Féin as the political wing of the Continuity IRA, a claim the party denies.

One motion recognises "the historic right of the Irish people to use controlled and disciplined force to drive the British forces of occupation out of Ireland". Another from a Newry cumann says the ard fheis "commends and salutes the Continuity leadership of the republican movement and congratulates them on their continued resistance to British rule in Ireland".

The Continuity IRA killed PSNI man Stephen Carroll (48) in March, two days after the Real IRA murdered two British soldiers at Massareene. There has been serious rioting this year in Ardoyne and Lurgan. One motion "applauds" the young people involved: "Their actions confirm that the flame of republicanism burns in the heart of a new generation".

Another resolution says Irish people who join the PSNI or collaborate with them "will be treated as traitors, spies and informers". Delegates will be asked to "actively oppose" British royal visits to Ireland.

In other debates, "the builders, bankers, bosses, developers, speculators and political establishment whose actions now result in the taxing of future generations to pay for their excesses" are denounced. The resistance of the Dublin dockers, Thomas Cook and Coca Cola workers are praised.
