STATEMENT FROM MANCHESTER CITY COUNCIL
"We are happy to confirm that there will be a parade in the early evening of Monday 13 May to mark Manchester United FC's title win, travelling from Old Trafford to Manchester City Centre. Full details will be announced in due course.
"We would also like to clarify that, contrary to the implication in some sections of the media today, Manchester City FC have never discussed or requested having a parade on Monday 13 May, or any other date.
Should they win the FA Cup and any suggestion about there being competition for that date is entirely unfounded."
