After the military staged a coup in 2014 to oust then-Prime Minister Yingluck Shinawatra, a ban was imposed throughout the country on all political activities.

This included a ban on any public gatherings of more than five people.

On Friday, the junta said in a statement published in the Royal Gazette there would be a "relaxation" on the ban.

Parties will now be permitted to elect their leaders, recruit new members and hold general party meetings if they are able to summon at least 250 members.

However, campaigning -- including holding public gatherings -- is still forbidden.

"Political parties can communicate with their members electronically, but that type of communication must not be considered as campaigning," the statement said.

The junta and the Election Commission would decide if any communications was "disrupting public order".

The junta has repeatedly postponed elections, but King Maha Vajiralongkorn this week endorsed two bills that cleared bureaucratic hurdles to a much-anticipated poll.

An election is required to take place by May.

Senior military leaders have floated a February 24 election date.
