'Undemocratic tactics'

The rather belated decision of the opposition parties from the platform of All Parties Democratic Movement (APDM), founded in London thousands of miles away from the soil of Pakistan, that their parliamentarians will resign from the legislatures cannot be appreciated in any manner, even by their own supporters.
The APDM parliamentarians, as reports have been published in the newspapers, will resign en masse from the national and provincial legislatures in protest against what they called the acceptance of nomination papers of General Pervez Musharraf as a candidate for contesting the forthcoming presidential election by the Election Commission. Prime Minister Shaukat Aziz, while commenting on this, has said that the opposition should have resigned two years as the assemblies are now completing their five years term.
Federal Information Minister Muhammad Ali Durrani has quite rightly asked the opposition parties to do something positive and bring forth their candidate for contesting the presidential election instead of continuing to indulge in negative and undemocratic tactics in this manner.
The opposition parties, who outnumber their parliamentarians, have a rather long history of threatening to quit the Parliament on this or that pretext and then never doing so. They have been indulging in such undemocratic negative tactics ever since the National and Provincial Assemblies came into existence after October 2002 general election. Is this their contribution towards strengthening of democratic institutions and furtherance of their electorates causes?
General Pervez Musharraf, as the Prime Minister stated is the unanimous candidate of the PML (Q) and the allies for the presidential election. But where are the opposition parties and their candidates to oppose General Pervez Musharraf in the presidential election?
