Organisers have been in touch with all the relevant authorities and the message is that Manchester is still open for business and the venue is open as usual too.
Extra security measures have been put in place for the event as a precaution.
The BDA has encouraged delegates to be mindful when travelling to the venue that there are some travel restrictions in place within the city. Live transport information is available from Transport for Greater Manchester.
The Greater Manchester Police have urged the public to remain vigilant, but to go about their daily lives. Updates are available from the GMP website.
Mick Armstrong, chair of the BDA, added,"We are proud to have made Manchester the home for our conference. We are saddened by the events of last night and our thoughts go out to those affected."
