Display Word Press Post on another webpage properly

Hey all

If you have a quick look at https://www.webtechglobal.co.uk you will see a rather quickly written post but the bigger problem is how <p> tags are missing from the html.

Obviously I use a basically SQL query to retrieve the last post made on my blog and display it by echoing the content field.

The results are not too impressive so I went through adding the <p> tags in html part of WP’s WYSIWYG however later on when I made a small update to the post it reverted back to its old ways.

Any suggestions on how best to display the data?

Thanks
