A plaque is to be installed in the House of Commons in memory of a former Sussex MP who died when the IRA detonated a bomb under his car.
Former Eastbourne MP Ian Gow, who was Margaret Thatcher's parliamentary private secretary, died in the blast on 30 July 1990.
The bomb was detonated in the driveway of his East Sussex home.
Commons speaker John Bercow said the memorial plaque would be placed in the Commons chamber.
Mr Bercow said: "The matter was considered at the House of Commons Commission meeting last night and I am pleased to advise the House that the commission decided unanimously that there should be a permanent memorial to the late Ian Gow and that would likely take the form of a plaque.
"That plaque will be put up in the chamber of the House of Commons, similar to the plaque that has been long-established in recognition of the distinction and the terrible fate of the late Airey Neave."
Tory MP Airey Neave was killed by a car bomb planted in the Palace of Westminster by the Irish National Liberation Army in 1979.
