Frank Field has said he will not trigger a byelection and will “fight any attempt at expelling me in every way I can” from the Labour Party.
Field recently resigned the party whip claiming the party was suffering from bullying and also that antisemitism was rife.
The Birkenhead MP said he would fight any attempt to expel him from the Labour party.
He said “I now have what may become a major legal dispute with the Labour party over my continuing membership of the party.”
Field added: “I shall fight any attempt at expelling me in every way I can and, if need be, in the courts. This interpretation of Labour’s rulebook could last a long time.”
He said he will continue to represent the people of his Merseyside constituency; “The whole of my time will continue, as in the past, with trying to serve Birkenhead to the best of my ability and spearheading a whole series of major projects in the town.
“I also look forward to contributing further to the development of the Labour party’s programme of social and economic reform.”
On the issue of Field’s resignation, Labour leader Jeremy Corbyn said: “I’m sorry he’s resigned and I thank him for all the work that he’s done as an MP and for the party, but I don’t see why he had to resign.”
