The move comes after Declassified, Belgian NGO Vredesactie, Irish news outlet The Ditch, and Palestinian Youth Movement discovered a suspicious package of military goods bound for Israel in March.

Belgium has strict laws on the transhipment of military items to Israel through its ports and airports, including a ban on overflights carrying weaponry through its airspace.

The shipment was seized by the Belgian authorities, which confirmed that it contained items covered by UK export codes for military aircraft and fire control components.

They did not refute that some of the items may have belonged to Moog, a US aerospace firm in Wolverhampton which manufactures trainer aircraft components for the Israeli air force.

Published this morning and authored by Steve Witherden MP, the letter is now asking the UK authorities to explain how an illegal arms shipment to Israel was exported from Britain.
