Ahead of their planned massive show of strength against the "puppet" regime of Madhav Nepal on May 1, Nepalese Maoists have intensified their anti-India campaign by releasing posters and pamphlets against New Delhi.

The former rebels are planning a major rally on May 1 to demand the ouster of the 22-party coalition government headed by Madhav Kumar Nepal, calling it a "puppet" regime, coinciding with the International Labour Day.

Ten days before the rally, walls in capital Kathmandu adorn posters and paintings against India, which authorities feel would further fan anti-India sentiments in Nepal.

"Get rid of the puppet government", "abrogate the Nepal India Peace and Friendship Treaty of 1950" and "Indian Army vacate Kalapani and Susta" are some of the slogans that have made way into the posters.

Some posters say the May one agitation is to protect "national independence and fight against colonial and expansionist forces."

Maoists have been accusing India of interfering in Nepal's internal affairs, but New Delhi has rejected it.

Last week, Indian Ambassador Rakesh Sood had met Maoist chief Prachanda to express concern that the rally would further fan anti-India sentiments in Nepal.

CPN-Maoist leader say the May 1 rally is to "fight against those forces which have been conspiring against the peace process and the process of drafting the constitution."

The party has also appealed to labourers to participate in the rally.
