I would like to do this presentation as a conversation!
I guess Brexit is the wrong direction for U.K
The presentation should be not less than 5 slides (title and references slides not included)
Add speaker notes too (50-100 words For each slide)
You should offer supportive arguments in terms of effects on the U.K. and/or other European countries based on impacts such as (you choose one from among these, or some other aspect you prefer) jobs, income, environment, economy, or society.
