The prediction of the "Brexit" referendum

I think that Britain will stay in the EU for a greater chance. Firstly, most of the businesses will benefit from staying in the EU. Secondly, staying in the EU will win support from the middle and upper classes of the British people. Thirdly, the assassination disguises people and may make some of Brexit supporters change their mind. Fourthly, the "staying in" group has increased their advertising effort. Many respected figures have expressed their support for the staying in. Based on these four reasons, I think that the staying in will win greater support.
