As far as I know, British security assistance to the Palestinians - which began while Fatah was ramping up a suicide war and has been turned against the IDF by Palestinian soldiers - continues apace. Not so much for the weapons Israel used in its defensive operation against Hamas:

Britain has slapped a partial arms embargo on Israel, refusing to supply replacement parts and other equipment for Sa'ar 4.5 gunships because they participated in Operation Cast Lead in the Gaza Strip earlier this year. Britain's Foreign Office informed Israel's embassy in London of the sanctions a few days ago. The embassy, in a classified telegram to the Foreign Ministry in Jerusalem, said the decision stemmed from heavy pressure by both members of Parliament and human rights organizations... The British said the embargo was imposed because these ships participated in Operation Cast Lead. In so doing, the British claimed, they violated the security agreements between Britain and Israel, which specify what uses may be made of British equipment.

I love the logic underlying this trick: "We'll sell you weapons but you can't use them against people who attack you."

It's the same logic that Obama uses when he demands that Israel take risks for peace - because who would dare threaten the territorial integrity of a nuclear-armed state - and then pressures Israel on its nuclear deterrent. It's not a particularly effective argument and it undermines Middle East stability by encouraging Arab intransigence. But at least it's also dishonest!
