Jack Straw and David Davis try to block prisoner votes
Labour's Jack Straw is joining forces with Conservative David Davis in an attempt to block plans to give thousands of prisoners the vote.
The former home secretary and shadow home secretary are seeking to trigger a Commons vote on the issue.
The pair want the government to defy a ruling by the European Court of Human Rights (ECHR).
Ministers say if they do not change the law they will face compensation claims from prisoners costing well over £100m.
