The house of representatives has summoned James Entwistle, the outgoing US ambassador to Nigeria, over the allegation of sexual misconduct levelled against three members of the House of Representatives.

Entwistle had written a letter to Yakubu Dogara, speaker of the house, alleging that Samuel Ikon (PDP Akwa Ibom), Mohammed Gololo (APC Bauchi) and Mark Gbillah (APC, Benue) allegedly sought the services of sex workers while they were attending a programme in the US.

The lawmakers denied the allegations but Dogara referred the matter to a joint committee on ethics and privileges and foreign affairs for investigation.

The committee has asked the ambassador to appear before it on Thursday.

The committee also invited the National Human Rights Commission (NHRC) and the three lawmakers alleged to have engaged in sexual misconduct.
