KATHMANDU: Top leaders of four major political parties on Sunday decided that Prime Minister Sushil Koirala will write a letter again to disgruntled political parties and groups for talks.

After various groups including Madhes-centric parties and those demanding a separate Tharuhat region staged violent protests in various parts of the nation against the proposed demarcation of federal units, the Prime Minister had sent them an invite for talks a few days ago.

The United Democratic Madhesi Front and the Tharuhat/Tharuwan Joint Struggle Committee, two major agitating groups, on Saturday had responded to the invite and demanded that their conditions be met for the talks.

The four major parties - Nepali Congress, CPN-UML, UCPN-Maoist and Madhesi Janaadhikar Forum-Democratic - had held a meeting to discuss next steps following the response, on Sunday.
