Keeping Gordon's hands off the money
Sisters Joy and Sybil Burden have a pact that whoever lives the longest will set fire to their Ogbourne home to prevent Chancellor Gordon Brown getting any inheritance tax.
Last week the spinster sisters appealed to the European Court of Human Rights to be treated the same as lesbian and gay couples.
Same sex couples are treated the same as married couples and are exempt from having to pay inheritance tax if one of them dies.
However the exception does not extend to siblings and the Misses Burden have been fighting for more than 30 years to get the law changed.
The sisters said they had never taken a penny from the state and all they were asking for was to be treated the same as married couples or same sex couples.
Joy Burden said: "Over the years we have come to understand more and more how corrupt this country has begun."
Their father Frank was a Methodist preacher besides being a farmer and he instilled in his sons and daughters a sense of justice and value.
The elder sister said: "If one of us dies then we have vowed that the other one will burn the house down rather than let Gordon Brown get his hands on this money.
