A motion calling for changes to the law following the case of Birkenshaw ambulance driver Mike Ferguson has been tabled in Parliament.

Mr Ferguson was charged with speeding after driving at more than 100mph through Lincolnshire while transporting a liver from a donor in Leeds to a patient in Camb-ridgeshire.

Although the case was dropped last month, Mr Ferguson, Spen MP Mike Wood and the GMB union have pledged to work together to make sure similar charges cannot be brought in such circumstances in the future.

Mr Wood tabled the early day motion before work starts in Parliament to bring the law up to date.

An early day motion is used by MPs to promote or comment on a particular issue and for other MPs to sign their names to in agreement. The more names and support it gets, the more prominent the issue can become.

Mr Wood has already contacted several MPs asking for their support on the controversial subject.

Before the relevant changes can be made, Mr Wood is seeking opinion and advice from all sides - ranging from the police to drivers in all the emergency services.

Mr Ferguson is also working on a code of practice for drivers who work in donor organ transportation.

Mr Wood said: "The law has not kept abreast of changes in the way our emergency services work. It is this which must be rectified. There is a lot of work to do. First of all, we are gathering as much professional opinion as we can to ensure that the change in the law is both comprehensive and relevant.

"Although cases such as Mr Ferguson's are rare, we are all conscious that what happened to him could happen at any time to another public servant going about his or her duty of saving lives.

"The early day motion will offer MPs a chance to express their opinion. Although it will not necessarily force a debate in its own right, the more support it receives the stronger our case will be."
