The group has contacted the AJ to threaten homeowners across the country, saying they are not 'innocent bystanders' and their vehicles will be targeted.
The HBLF unveiled its manifesto in March claiming it had been forced to fight to protect old buildings as a result of 'developers' greed and planners' indifference' (AJ 30.3.06).
One of the group's most high-profile attacks to date was on the offices of the Hitchin Youth Trust in Hertfordshire - which were due to be pulled down - where paint was thrown over trust members' cars.
But this local campaign is now set to escalate dramatically. In its latest letter, the group says it intends to 'attack new-build that has been built at the expense of historic buildings', as well as the property of residents.
The letter continues: 'The situation is thus: John Prescott, who's unscrupulously bent on destruction, in the position of deputy prime minister, in an unpopular Labour government, in one of the safest seats in the country, is doing what the hell he likes to our heritage.
'This is the democracy we have at this present moment in time, and it's a democracy that reeks of corruption.
'This country belongs to the nation, it's not his alone to carve up how he sees fit. Anyone who opposes his plans should take up whatever action they can.'
