The centre circle of Spurs' planned new £400million stadium would be exactly where the Archway Sheet Metal Works stands now.

The factory is the final business standing in the way of the redevelopment and the firm is challenging a compulsory purchase order approved by Local Government Secretary Eric Pickles in July last year.

In a packed High Court this morning Christopher Lukkart-Mummery QC representing the metal works presented two of the three grounds of contention, including the legality of the CPO and the certainty that the stadium would be built.

In his opening statement the barrister revealed that the family business stands precisely on the spot where the new centre circle for the ground would be.

The QC outlined reasons why the compulsory purchase issued by Haringey Borough Council might not be valid.

He said: “When planning permission is granted by the council it is assumed to be valid unless it is challenged or proved to be otherwise. In this case the Secretary of State for Planning made this assumption."

He then used cases dating back to 1948 to claim the assumption of legality of the CPO did not apply to the application of the 56,000-seater stadium.

Mr Lukkart-Mummery said: “The club stated unequivocally that it was not intending to move away from Tottenham as part of application for planning permission.”

But he used Spurs’ application to take up residence in the Olympic Stadium to counteract the claim 

Before adjourning for lunch, the QC moved onto his second ground, certainty of delivery and "whether the financial viability gives confidence that the project will be a success”.

After lunch, Mr Lukkart-Mummery will move onto the final grounds, which will be ‘material changes to the scheme’.
