It’s on: Eastwood confirms challenge against McDonnell

Just in from the Irish News political correspondent, John Manley

I would imagine some backers of his push will involved Mark Durkan MP and Claire Hanna. Backers of McDonnell will include Fearghal McKinney and Alban Maginess.

Some key folks to watch in terms of who they side with are the former leader Margaret Ritchie, former minister Alex Attwood and Patsy McGlone.
