Sinn Féin's Martin McGuinness has called for immediate talks to be convened by the British and Irish governments on the political impasse in Northern Ireland.

The Deputy First Minister welcomed Taoiseach Enda Kenny's comments this morning that he is to meet the British government to discuss the issue.

He was speaking on the way in to the second day of his party's "think-in" at Termonfeckin in Co Louth.

Mr McGuinness said he had spoken to Minister for Foreign Affairs Charlie Flanagan by phone regarding his comments criticising the parties involved in the process.

He said he was not interested in getting into a spat with the governments, but he said complacency had crept in.

Mr McGuinness said the Government needed to hold the British government to account and needed to be a champion for the Good Friday Agreement.

He criticised the DUP for failing to implement the agreed programme for government in Northern Ireland.

His comments come at the end of a week when First Minister and DUP leader Peter Robinson expressed his concern about delays, disagreements and "unsatisfactory compromises" facing ministers at Stormont.

Mr Robinson called for a fresh round of negotiations on the scale of the 2006 St Andrews Agreement.

Members of the powersharing government at Stormont have been at loggerheads over issues such as dealing with the legacy of the conflict, controversial flags and marches, as well as welfare reform.

Mr McGuinness also had sharp criticism for his DUP colleagues when he later spoke to the conference.

He said the DUP was accepting devastating cuts being inflicted by the British government on the weakest in society.

Mr McGuinness criticised the DUP for saying that the institutions were not fit for purpose, saying that the DUP was not fit for purpose.

He also said Unionist politicians routinely excuse and defend racism, sectarianism and homophobia.
