Chelsea's Russian billionaire owner Roman Abramovich has put the club's stadium plans on hold after delays to the renewal of his UK visa.
The estimated cost for a new 60,000 seat Stamford Bridge has increased to £1bn after delays, which included a dispute with a local family.
Abramovich is unwilling to invest in a major project in a country where he is not allowed work.
The 51-year-old's UK investor visa expired some weeks ago.
The BBC's Daniel Sandford says visa issues could be a consequence of the Skripal case or simply red tape.

Russian billionaire Roman Abramovich has topped the Sunday Times Rich List for the Channel Islands in 2018.
With a 2018 wealth of £9.3bn Mr Abramovich is followed by the Barclay brothers, Sir David and Frederick with £7.4bn.
The journalist who compiled the list, Robert Watts, said the newspaper had confirmed Mr Abramovich had applied and been accepted for high value residency status in Jersey, but has not yet taken it up.
A States of Jersey spokeswoman said the Chelsea Football Club owner's residency status "has not been confirmed by any government office" adding the States were unable to comment on individual residency cases.
