"economical with the truth" in his claims to have broadened the base of donors to the Tory Party.
Now he has been caught out by The Sun telling a story about his last pasty - or was it a "porky pie"?
When challenged about the last time he eat a pasty Cameron said "I seem to remember I was in Leeds station at the time and the choice was whether to have one of their small ones or large ones. I have a feeling I opted for the large one — and very good it was, too."
Rashly, Mr Cameron added: "I am sure The Sun will have someone rushing up to the shop right away to check it out." And they did.
It soon emerged the West Cornwall Pasty Company does NOT have an outlet at Leeds station — because it closed in 2007. There was another pasty seller, Cornish Bakehouse, at the station. But it SHUT last week after Chancellor George Osborne announced the VAT hike in his Budget
Cameron denied the Government's plan to slap 20 per cent VAT on hot pasties, pies and sausage rolls shows they are out of touch with hard-pressed workers, families and students - just another Coalition tax.
And absurdly, if your pasty goes cold while you are waiting to pay at the till, it's no longer subject to tax. Who will know? Will there be an army of under-cover tax inspectors testing the temperature of a student's pasty in Greggs on Christchurch Road?
The Coalition Government - untruthful and out of touch.
