Home Secretary Theresa May is expected to announce a review today of whether to introduce a statutory time limit on how long people can be kept on police bail as well as action to curb police spying on journalists' phone records.

In recent years at least 63 journalists have been arrested as a result of investigations stemming form the hacking scandal. Some have spent years with the careers in limbo whilst on police bail.

For some, the gap between arrest and trial is looking at being around three years.
