(Reuters) -Last week's landmark ruling on trans women in Britain will not impact Sunday's London Marathon, with race director Hugh Brasher saying he supports a recent World Athletics decision to gender test to "protect women's rights to compete fairly".

Brasher added he will wait for guidance from the Equality and Human Rights Commission (EHRC) and Sport England before deciding if changes are needed for future editions of the London Marathon, which currently permits runners in the mass race to self-identify their gender, but restricts entries in the elite and championship races to females at birth.
