Conservative leader David Cameron is expected to urge all politicians to work together to combat terrorism.
In a speech at the International Institute for Strategic Studies, he will say point-scoring by rival parties is undermining efforts.

Lord Carlile, overseeing terror laws, expects new plans, possibly including allowing detention of suspects for up to 90 days, to be published next year.
But Tories, Lib Dems and Labour rebels voted down this proposal last year.
'Evidence needed'
They argued that it would undermine civil liberties and said such a period for questioning and investigating suspects was unnecessary.
There is uncertainty about the government's plans.
Prime Minister Tony Blair has said he still backs plans for an extension from the current 28 days to 90 days, but wants to proceed by consensus.
However, at the weekend Attorney General Lord Goldsmith said ministers "need evidence" to demonstrate such an extension is needed.
Shadow home secretary David Davis said: "What the attorney general is saying is, what we thought all along, that there's no evidence there to argue for more and that 28 days, as it stands, is sufficient."
Last year, the Commons turned down the government's plans for a 90-day limit, with MPs and peers eventually settling on a maximum of 28 days' detention without charge, extending the limit from 14 days.
