The DWP says people expecting benefit and state pension payments today and tomorrow might not get their money until later in the day.
Last week, the DWP issued an update that payments due on Tuesday September 20 and Wednesday September 21 will be paid "throughout the day".
People who rely on benefit, state pensions and tax credits woke up in panic today as they found they had not received their payment. Many took to social media to vent their frustration.
