A planned memorial for British victims of terrorism is to be located at the National Memorial Arboretum in Staffordshire, David Cameron has announced.
A panel headed by former overseas development minister Baroness Chalker will now be appointed to select an artist and design for the site.
The announcement follows a public consultation on the choice of location for the memorial which will be formally unveiled in summer 2017.
A separate consultation is to be launched for a memorial for the victims of the Sousse and Bardo Museum terrorist attacks in Tunisia in 2015.
Speaking before leaving the Nato summit in Warsaw, Mr Cameron said: "These memorials will be places where the family and friends of people killed in terrorist attacks can reflect and remember. By building them we are underlining our pledge to never forget the victims of these atrocities.
"An attack on British people anywhere in the world is an attack on us all. But these memorials will also stand as proof that we will not give up our way of life in the face of terrorism wherever it may be."
