Is the right hon. Gentleman aware that, whatever criticisms we may have made of his last statement, we well recognise the extra strains placed on him at this time when such a problem arises? On this statement we entirely support what he said. What has happened is clearly a new development and, like all new developments in this area, it requires careful security on all sides, careful action by the police and the fullest possible co-operation between the police and the public. Of course, I join the right hon. Gentleman in condemning such attacks. He and I have both had experi- ence of condemning such attacks over, alas, far too long a period.
