Martin McGuinness has backed calls from unionist politicians for the removal of a Union flag placed in the grounds of a Catholic Church near Ballymoney.
The flag was reportedly placed on top of an electricity pole which sits inside the grounds of Our Lady and St John the Evangelist Church in Dervock.
The DUP mayor of Ballymoney, Bill Kennedy, said it was "totally wrong" to put the flag up in the church grounds.
"There's many other places in Dervock where they could put their flags. To put one inside any place of worship without permission is totally wrong and I hope that common sense will prevail and they will take it down. It doesn't help anybody's cause," he said.
Ulster Unionist North Antrim MLA Robin Swann also called for the flag to be taken down. "All places of worship of whatever denomination are entitled to be shown respect," he said.
Mr McGuinness wrote on Twitter: "If a Tricolour was erected in the grounds of a Protestant Church I would take it down. Union flag at Dervock Catholic Church should come down."
The three most senior Orangemen in Northern Ireland took part in a loyalist march to express solidarity with their angry brethren in north Belfast last night – but kept details of their protest plans under wraps.
