Amid a walkout by Congress-led United Democratic Front (UDF) opposition, the Kerala assembly on Monday passed a resolution alleging that chief minister V S Achuthanandan was ignored during the recent visit of prime minister Manmohan Singh to the state.

The resolution moved by law minister M Vijayakumar after nearly hour-long heated exchanges between the ruling Left Democratic Front (LDF) and opposition members also decided to apprise the centre of the state's resentment on the matter.

The matter raised by Anathalavattom Anandan (CPIM) through a submission virtually turned into a debate with Achuthanandan and some of his cabinet colleagues narrating their experiences during the prime minister's February 10-12 visit.

Achuthanandan said he was not allowed a room at the Taj hotel at Kochi where Singh stayed overnight on arrival on February 10.

LDF members alleged that it was an insult to the state as a whole, as the chief minister's name was not inscribed on the plaque which was unveiled by Singh at the inauguration of the International terminal at the airport here.

They also said the media advertisement for the inauguration of Vallarpadam transhipment terminal did not have the chief minister's picture.

Opposition leader Oommen Chandy said it was very unfortunate that LDF was converting the prime minister's visit into a controversy by raking up issues like this and walked out of the house with UDF members.

Ministers Elamaram Kareem and C Divakaran also narrated their experience when they went to the brahmos aerospace here as state's representatives during Singh visit to the unit.

The grievance in this regard had been voiced by Achuthanandan in the presence of Singh at the airport function on February 12. He had also stated that the state government had been neglected, but it did not take it seriously as realisation of the projects was more important.
