ANGELA EAGLE may have to rely on wealthy Blairites to fund her coup after trade unions rallied behind Jeremy Corbyn.

Ms Eagle finally pulled the trigger on the faltering putsch against Mr Corbyn yesterday, filing the paperwork needed for a leadership challenge before holding court with reporters in Westminster.

But she could face funding problems because without the support of unions who backed her campaign for the party’s deputy leadership last year, in which she finished fourth of five with 16 per cent of first-preference votes.
