Party affiliation

Syed Farhat Ahmad Roomy, New DOHS, Dhaka
Some leaders of at least two political parties were elected members of parliament (MP) using Awami League (AL) symbol i.e. boat. Reportedly, these parties are registered with the Election Commission (EC) and were allotted respective party symbols e.g. hammer, torch etc. Certain questions obviously come to one's mind. a. Do these MPs come under the command and control of the AL parliamentary party? If so how can they project and promote their own party agenda in parliament, given the provisions of Article 70 of the constitution? b. If these parties have not used their allotted symbols in parliamentary election when would they ever use those? c. Is it justified for these parties to remain registered with the EC? Hopefully, some of your esteemed and knowledgeable readers would throw some light on the subject.
