Christmas cards may not be delivered until February due to usual seasonal backlogs worsened by strikes, it is reported.
Mountains of post have already been pictured outside Royal Mail centres due to industrial action and that was before a fresh walkout by 115,000 posties on Friday.
New advice is now to send items sooner than originally suggested with the postal service moving last posting dates forward as more strike dates were announced by the Communication Workers Union (CWU).
