While the IRB was instrumental in the establishment of the Volunteers, they were never able to gain complete control of the organisation. This was compounded after John Redmond, leader of the Irish Parliamentary Party, took an active interest. Though some well known Redmond supporters had joined the Volunteers, the attitude of Redmond and the Party was largely one of opposition, though by the Summer of 1914, it was clear the IPP needed to control the Volunteers if they were not to be a threat to their authority. The majority of the IV members, like the nation as a whole, were supporters of Redmond (though this was not necessarily true of the organisation's leadership), and, armed with this knowledge, Redmond sought IPP influence, if not outright control of the Volunteers. Negotiations between MacNeil and Redmond over the latter's future role continued inconclusively for several weeks, until on 9 June Redmond issued an ultimatum, through the press, demanding the Provisional Committee co-opt twenty-five IPP nominees. With several IPP members and their supporters on the committee already, this would give them a majority of seats, and effective control.
