He is seething that while up to £200million is being spent on the controversial Saville Inquiry into the events of Bloody Sunday, 666 victims of IRA attacks in this country, including the Aldershot seven, are being forgotten.
He said: "I think it is entirely right and proper that as MP for Aldershot I should raise the concerns, not only of the families of the 666 people murdered by the IRA in the UK, but specifically the families of the Aldershot seven.
"I read the comments of Mr Bosley, whose mother died in the Aldershot attack, and I agree that it was appalling that he should be offered just £1,500 compensation when these left-wing lawyers at the Saville Inquiry are on nearly £2,000 a day. It is absolutely offensive."
Mr Bosley had also raised the issue of the memorial.
It was initially placed in front of the town hall, but there were complaints that it was behind a mound and not visible from the road.
Some years ago it was switched to the site of the attack — the old 16th Parachute Brigade Officers' Mess off Pennefather's Road — but there is no public access there.
Mr Howarth revealed that he has already opened talks with Andrew Lloyd, chief executive of Rushmoor Council, about the possibility of having a "small and discreet" memorial ceremony on February 22 — the 30th anniversary of the Aldershot tragedy.
He added: "We need to let the families know what our thoughts are.
"I feel a sense of injustice on behalf of the people of Aldershot that nobody is remembering the callous and wanton murder of six civilians and one Roman Catholic padre, which was an act of direct retaliation.
"In response to all this milking of the Londonderry grief, as Aldershot's MP, I feel that justice should be done for the 666, but especially for the people of Aldershot."
Mr Lloyd said he was happy to liaise with Mr Howarth and the Garrison Commander over the possibility of having a ceremony on February 22.
He added: "It seems fitting. Perhaps there could be a ceremony involving the Mayor on the site of the memorial.
"It is a helpful suggestion and we will talk to the Garrison Commander."
Mr Lloyd confirmed that there is mention of a memorial for the victims under the council's Connaught Project, but this is a 25-year plan and it is not yet clear what form the memorial would take, when it could be placed and whether there would be public access.
However Mr Lloyd did pick up the current mood that a permanent public memorial is what is required.
He said: "We are a caring community organisation and we would always want to listen to people on such a sensitive issue as this.
"There has always been enormous sympathy for the victims of the IRA attack here, and their families.
"It has always been thought that the families were comfortable with the memorial, but if the current mood is for something more visible and public, we would not want to obstruct that.
"I would certainly want to listen and hold discussions with the cabinet."
