Legal moves to save the constituency of one of Gordon Brown's key allies will go on, a Labour MP insisted yesterday.

Jon Trickett (Hemsworth) said he would continue to fight the decision by the Boundary Commission to scrap the West Yorkshire seat of Normanton, held by Ed Balls.

Mr Balls was chief economic adviser to Mr Brown and is now Economic Secretary to the Treasury.

Mr Trickett said despite the decision by Wakefield Metropolitan District Council to stop legal action against the commission, "the fight to hold them to account will go on".

He said he would pursue the matter in Parliament and the courts, adding the commission "behaved outrageously".

A commission inquiry by assistant commissioner Frances Patterson recommended the constituency be retained as one of four Wakefield district seats.

But the commission announced in January it had not accepted her findings and intended to cut the district to three seats.

Yesterday Mr Trickett said: "The Boundary Commission have behaved outrageously in their review of West Yorkshire and the fight to hold them to account will go on. The legal advice to Wakefield Council is extremely strong, showing a 60 to 70 per cent chance of success. It is my intention, and that of other local MPs, to continue to pursue this in Parliament and the courts."
