asked Her Majesty's Government:

Further to the Written Answer by Lord Rooker on 25 March (WA 84), how many successful convictions have taken place in each year since 1970 in connection with the murder of police officers in Northern Ireland. [HL2830]

As indicated in my previous Answer (WA 84), information recorded on convictions does not include details of the victim. Obtaining accurate statistics on the number of successful convictions in connection with the murder of police officers in Northern Ireland would, therefore, require a manual trawl of each case and could be carried out only at disproportionate cost.
