Leigh Griffiths has apologised for accidentally liking a tweet which referred to Rangers fans as "dirty orange b*******".

The Celtic hitman made the mistake earlier when he liked the post which included the sectarian jibe. The tweet showed footage of Gers fans earlier this season singing 'Welcome to the Party'.

Glasgow Times:

But it ended with a clip from Still Game saying 'The Party is over'. The caption of the tweet was the issue, however. It read: "We're back timmy, 55 is happening! Tell everyc**t you meet, the teddy's are back!!!

"Hahahahaha the banter years continue. Get it up everyone of you dirty orange b******s." Griffiths, 29, had initially hit the like button before later holding his hands up to accept his mistake - but reiterate that it was just that.

He said: "So you press something by mistake then fix it …and it still becomes world news. Pathetic. Wasn’t even aware of it until someone told me. Sorry for the error."

Celtic stretched their lead at the top of the table to 10 points last night with a 5-0 win over Hearts while Rangers slipped up again to lose at Kilmarnock.
