Alison Guthrie, 45, and her partner work part-time in the voluntary sector, earning about £28,000 a year between them.
They live in Glasgow and have four children at home aged four to 16. The couple receive £240 in child benefit 13 times a year, and £600 a month in tax credits.

"Freezing fuel duty is something we welcome. We can spend between £200 and £250 a month on petrol so any help with this is greatly appreciated.
