There are currently reports in the mainstream press and other media outlets that British Foreign Secretary William Hague met with Israeli politicos in Jerusalem.
It would appear that the Israelis are complaining that they have to follow the rule of law. In particularly the one about suspected war criminals having to face trial and answer for their actions such as the murder of very many civilian children, women and men. They have been accused of committing war crimes and crimes against humanity in the West Bank, Gaza and on internationally governed high seas.

The reports go on to suggest the British government may waver the rules concerning universal jurisdiction when it comes to Israeli politicians, generals and other military personnel. Despite the UK having signed up to such international treatise drawn up by the United Nations General Assembly.
see article 111 in the Introduction of Amnesty’s Report headed:
THE WIDESPREAD ACCEPTANCE OF UNIVERSAL JURISDICTION AND THE OBLIGATION TO EXTRADITE OR PROSECUTE

There is much evidence of Israel committing war crimes during the 2008/2009 assault on Gaza named Operation Cast Lead.
Some of this is recorded in an extensive and though United Nations report chaired by justice Richard Goldstone.

If the British government were to rewrite or ignore this legislation then it would set a precedent allowing those in favor to be above the law thus encouraging a society even more lawless than it currently is.

Much trade is already conducted between the UK and Israel despite its shocking human rights record to wards many foreign nations particularly the Palestinians.
One example being the arms trade and the exchange of knowledge and money in the development and use of Unmanned Ariel Drones.
Case Study Gaza City am house
On January 4, at around 3pm, an Israel Defence Force (IDF) drone launched a missile at six children playing on the
roof of the al-Habbash family home in the al-Sha‘f area of Gaza City. The missile killed two girl cousins, aged 10
and 12, and injured three other children, two of whom lost their legs:
Human Rights Watch interviewed Muhammad al-Habbash, 16, one of those injured in the attack. “We were playing as
we used to do every day, running around. There were drones flying overhead,” he said. “We stood near the edge of the
roof looking down to the street… I was thrown into the air and ran to the stairway amid the smoke.”
Muhammad al-Habbash, the father of one of the dead girls, Shaza, and a science teacher at an UNRWA school, was
downstairs when the missile struck. “We keep chickens on the roof and the kids were feeding them and playing,” he told
Human Rights Watch. “We heard the drone above, but it was always flying around.”

Sovereign drones
While the British government is buying and renting US and Israeli
drones, it is very keen to develop its own ‘sovereign’ drones
made by BAE Systems, Britain’s largest arms manufacturer. BAE
have been developing several drones since 2002. The most
likely to reach production stage are Mantis and Taranis.
