Defence minister Nirmala Sitharaman on Thursday announced Tamil Nadu will host the biannual defence exhibition, Defence Expo, in April. The exhibition will take place from April 11 to 14 in which nearly 80 countries are expected to take part. \u201cThere have been queries regarding the expo as to why it got delayed. I must say that there was no delay. After the Cabinet reshuffle in September last year, we started the process,\u201d she said in her address at the two-day defence industry development meet in Chennai. Sitharaman said the ministry officials had earlier visited several states to hold the event and the Tamil Nadu government immediately came forward and allotted land for the same on the East Coast Road near Mahabalipuram. \u201cUsually, the event is conducted by February-end. Because of certain changes in the ministry, we had to take a call and I am grateful to the Tamil Nadu government for having helped us by providing land,\u201d she said.
