Sinn Féin must talk with DUP - Ó Cúiv
Fianna Fáil TD Éamon Ó Cúiv has warned Sinn Féin not to "play political games" with the Irish language question.
The Galway Gaeltacht TD, who is a strong supporter and speaker of the Irish language, has also urged Sinn Féin to engage seriously with the Democratic Unionist Party on re-establishing power sharing in Belfast after a nine-month lapse.
Mr Ó Cúiv took to Twitter twice yesterday to express his strong views on the issue.
"Movement is needed to re-establish the Executive. SF is playing political games with the language question," he tweeted.
He also echoed the criticisms by Fianna Fáil leader Micheál Martin at the weekend about the swift and abrupt way an approach by Democratic Unionist leader Arlene Foster was rebuffed by Sinn Féin.
"Disappointed SF didn't give more consideration to Arlene Foster's offer.
"Her remarks were significant re her approach to the Irish language," Mr Ó Cúiv commented in another tweet.

Fianna Fáil has consistently criticised both of the main Northern Ireland parties, but aimed at Sinn Féin with increasing stridency in recent weeks over the failure to get power sharing back on track. Mr Martin has accused Sinn Féin of not caring about ordinary working people's jobs, which are at risk from the Brexit fallout.
Sinn Féin has said an Irish Language Act is required before any power sharing can function again. Fianna Fáil, in common with other parties on the island, broadly supports that view but argues that Sinn Féin needs to be more flexible.
In the past, Mr Ó Cúiv has been more friendly towards Sinn Féin and at one stage fell out with his party leader on the issue. But in recent days he has strongly backed Mr Martin's insistence that there can be no coalition between the two parties after the next election.
