What do these articles have to do with you unquestionably linking to Gilligan's poorly researched article? Corbyn et al's links with supporting the Irish unionists cause against the British state is well documented and well rooted in opposing the British State's use of apartheid tactics in Northern Ireland in the late 60s, as well as their own use of weapons on a peaceful NI Labour Party march that triggered the Troubles in the first place. If you're interested, read up on it but read both sides of the debate, not just unquestioning acceptance of your own Starte just because you happen to have been born there.
