A mother-of-two who made £20,000 worth of bogus child tax credit claims was caught after posting photographs on Facebook of her family holidays.
Joanna Pawlicka claimed she was a single mother as she spent more than five years claiming benefits she was not entitled to, a court heard.
An investigation was launched after the benefits agency was given a tip-off that Pawlicka was living with her husband Dawid Borucki and he was working full-time.
