The UK government has cautioned its citizens against participating in political activities while in Nepal.

In a newly-updated travel advisory, the UK has warned its citizens that they 'may be liable to penalties including deportation and/or a fine' if 'involved in any political activities' in Nepal, where Madhesi and Janajati parties have been spearheading an agitation to exert pressure on the ruling coalition and the main opposition to rewrite the constitution.

The UK updated its travel advisory on Nepal after the arrest early this week of a British national for 'participating' in a political rally organised in Kathmandu by the Federal Alliance, which is a coalition of Madhesi and Janajati parties. Martin Travers, 44, was later released after immigration officials concluded that he was just a bystander.

Early this month, a Canadian man, Robert Penner, was deported from Nepal for posting 'a provocative tweet aimed at spreading social discord in Nepal'.

On Friday, Kantipur daily quoted Kedar Neupane, the Director General of the Department of Immigration, as saying: "Previously, we used to deport only those foreigners found involved in serious crimes. Now, even those foreigners who are found involved in Nepal's internal political affairs will be deported or/and fined."
