- Around 200 so-called letters of assurance were sent to fugitive Irish republicans telling them they were not wanted by British authorities
- The letters were sent to sustain the Northern Ireland peace process
- A senior police commander told MPs that 95 of the people who received letters were linked to 295 murders during the Troubles
- The prosecution of a man accused over the 1982 Hyde Park bombing collapsed when it emerged he had been wrongly sent a letter of assurance in 2007
Lady Justice Hallett confirmed there are two other cases where letters were sent in error in a scheme which was kept quiet.
The findings of a four-month inquiry into On-The-Runs letters are unlikely to appease the families of IRA victims.
