Sport reacts to London explosions

Sporting bodies have been quick to pay their respects and reassess security plans following the London bomb blasts.

Cricket officials will meet on Friday to discuss arrangements for the two remaining England-Australia matches at Lord's and The Oval respectively.

Thursday's racing at Epsom was called off, but Sunday's British Grand Prix at Silverstone and next week's Open golf at St Andrews will go ahead as planned.

There will be a minute's silence before Saturday's Lions Test in Auckland.
