Three thousand delegates at this weekend's Sinn Féin Ard Fheis will debate 171 motions including ones on abortion, Brexit and entering government after the next election.

Two key motions focus on the party's position in relation to the upcoming legislation which will effect to the referendum on the Eighth Amendment.

The first states that the party will legislate in line with the views of the Ard Comhairle.

The other motion, proposed by 24 cumans north and south of the border, calls for members to be allowed to vote according to their conscience.

The party's Finance Spokesperson, Pearse Doherty, has stated that similar conscience motions at four past Ard Fheiseanna have been defeated.

He also stated that members who vote against the party's position on the legislation in the Dáil will face suspension but the length of this is not clear.

Another motion this weekend calls on the party to run a candidate for the presidency. Mr Doherty said the matter is under consideration and will be a matter for the Ard Comhairle at a later date.

Delegates will also debate a motion that that the only objective after the next general election should be to form a left wing government.

An amendment has been put forward by the Ard Comhairle to state that such an outcome should be attempted but should not be the only objective.

There are also motions calling for a referendum on Irish unity.

At the press event to launch the Ard Fheis programme, Mr Doherty clarified that it is up to each member of the party to voluntary pay back some of their Dáil salary to the party to re-invest in its constituency activities.

However, he said some members had arrangements but he could not say how many.

The party will also debate a motion for RTÉ to boycott the Eurovision Song Contest, which will be held in Israel next year.
