Why so noteworthy? Well, off the top of my head, this is the first time that Cameron has referred to the current system as a "tax on marriage". In which case, you wonder if the Tories are planning to place more emphasis on the financial, rather than social, implications of their marriage tax break; appealing more directly to pockets than hearts. Either way, the battle for the aspirational vote seems to be heating up.“
“Middle Britain has had a wretched time under Labour. This Government has taxed mortgages, marriages, pensions, petrol and travel and raised national insurance and the top rate of income tax. We cannot keep squeezing hard-working families."
P.S. Just out of a mild sort of interest, it's worth comparing and contrasting this Daily Telegraph leader from 2006, which says of Brown:
"He has taxed marriage and mortgages, petrol and pensions, homes and holidays."
