Israel has indicated that it plans to annex Jewish settlements in the West Bank with the blessing of the United States. The United Kingdom should not accept a land grab which could destroy any prospect for a peaceful solution to the Israel/Palestine dispute. The best way to respond to this is to threaten to, and if necessary impose, sanctions against the state of Israel to penalise it for any unilateral action that does not have the required support of the U.N.
