HH,
Corbyn made a comment not long after becoming Labour leader about coming to a negotiated agreement with Argentina over the future of the Falklands, including joint governance.
A slightly biased link, but it gives the background to Corbyn's stance:
Jeremy Corbyn's Falklands plan tantamount to surrender to Argentina, warns wounded veteran Simon Weston - Telegraph
I noticed that the Tories made a comment, no doubt in response, that the Falklands was safe on their "watch". Perhaps the new patrol/research vessel is in part making good on that commitment?
