British Ambassador to Nepal, Andrew James Sparkes, paid a farewell call on Prime Minister Sushil Koirala.

Ambassador Sparkes is leaving Nepal without completing his stint in the Himalayan nation. He has made the decision to leave British Foreign Service after thirty years service and three Ambassadorial posts.

In December last year, he was under controversy for reportedly lobbying for right to religious conversion in the new constitution of Nepal reports THT Online.

PM's press coordinator Prakash Adhikari said Koirala and Sparkes reviewed the latter's tenure in Nepal, Nepal-Britain bilateral ties and existing political condition.

The Prime Minister told the outgoing envoy that he would devote himself to peace, stability and development of the nation, according to Adhikari.

He also assured that the new Nepali constitution will promote and protect rights of all religions, languages, cultures and traditions of the nation.

Koirala told Sparkes that ruling parties are working on to resolve the existing deadlock through dialogues and expedite the constitution writing process.

In response, the Ambassador praised the Prime Minister's efforts for talks and wished him all success for the constitution writing, Adhikari said.

Meanwhile, the British diplomat said his stay in Nepal has been memorable to him and he was connected to Nepal emotionally.  Sparkes was working in Nepal since April 26, 2013.
