A Facebook post describing Celtic Park as “the piggery” has emerged online from the account of new Rangers PR chief David Graham. 

DUP Councillor and senior Orange Order figure Graham is set to replace Jim Traynor as the new head of communications at Ibrox after standing down from his position representing the Balmoral district of Belfast.

But his appointment has caused a social media storm after footage emerged of Graham rousing a crowd with a "no surrender" speech about unionism.

Now, in the latest controversy surrounding Graham’s selection - a Facebook post has surfaced online appearing to show the new Gers comms chief describing Celtic’s stadium in a grossly offensive manor. 

The post from 2011 refers to a YouTube video about the Rangers debut of ex-Gers ace Mark Walters. And on Graham’s “Meharg Davy” Facebook page, the post read: “Nothing changes at the piggery.” 

The Facebook statement has since been deleted. 

In footage that emerged this week, Graham donned a Gers shirt and talked about unionists' fighting spirit while referencing the Ulster Covenant signed in 1912 by those opposing Prime Minister Henry Asquith's plan for Irish home rule.

Graham says: "We as Rangers fans have that identity with unionism, loyalism and Protestantism.

"I know when our forefathers went and signed the Covenant 107 years ago as it was now today, I bet you then republicans and nationalists were saying 'I bet the union will never last and it’ll never see 1920.’

"Well the union is still here and it’s still strong because of our fighting spirit.

"It’s very easy as Rangers fans and unionists to take the flack and to lie down, but our cry has been since 1688 and always will be No Surrender."

Graham, who describes himself as a boyhood Rangers fan, was previously a special adviser to Education Minister Peter Weir before the Stormont Assembly collapsed in 2017.

He told the BBC: "As a lifelong Rangers supporter, it is an honour to work for the world's most successful football club. When the opportunity arose, I was very pleased to fulfil this role and am looking forward to getting started.

"I am excited by the board's vision for Rangers as we work towards our 150th anniversary and beyond."

Commenting on the appointment, Rangers managing director Stewart Robertson added: "David shares our vision, passion and enthusiasm for the club.

"We are delighted David has chosen to join us and strengthen our team. He is a welcome addition and I look forward to working with him."
