Should Britain end arms sales to Israel?

The row over arms sales to Israel continues today, as over 600 high profile figures in the legal profession, including former Supreme Court Justice Jonathan Sumption, sign a petition arguing they believe Israel has breached international law, and more Conservative politicians say, on the record, that they believe the UK must respond with an arms sale ban. Cindy Yu talks to James Heale and Isabel Hardman about where this row could go next. Produced by Megan McElroy and Cindy Yu.
