PRIME Minister David Cameron has given an absolute assurance the Hillsborough debate will not be waylaid.

Speaking at this afternoon's Question Time, the PM said: "We will not allow antything to eat into this very important debate."

It followed Liverpool MP Steve Rotheram attacking Dorset Conservative politician Christopher Chope who raised an objection about a previous debate on MP's own pensions, taking place on Monday afternoon, only lasting for two hours.

Mr Rotheram said: "In the real world, people won't understand that some people  would rather debate their own pensions rather than a 22 year old injustice will want to discuss."

Earlier, Mr Chope was under fire after politicians rounded on him.

Shadow health secretary Andy Burnham said 140,000 people signed the petition and “they will regard what’s just happened with great dismay.”

He added: “Surely it cannot be right for one member to stand up because he wants to talk his own pension to deny the opportunity for those people to debate the important issues relating to the Hillsborough disaster and the huge injustice that was done to the families and the people of Liverpool.”

Jamie Reed (Lab, Copeland) said it was “something which I think should and must haunt him for the rest of his days”.

But Commons Leader Sir George Young insisted that the Hillsborough debate would go ahead as scheduled on Monday.

Sir George said: “The government recognises the strength of feeling about this.”

The motion on limiting the pension debate to two hours would be debated and voted on in the  Commons today.

Wirral South MP Alison McGovern has expressed her frustration towards Chope: “I am angry that one rogue MP has tried to trample over the feelings of families who have waited so long to get answers to questions they have had for over twenty two years.

“I hope that the Leader of the House sees sense and leaves the days business as it was. The importance of this issue to the people of Merseyside cannot be underestimated”.
