//12.02 NJ , Brexit was all about Immigration and don't let anyone tell you otherwise. OK.//
Since you seem willing to engage in a reasoned debate, Gully, we’ve done this before. I can’t speak for anyone else, but immigration was not a deciding factor for me (it was not an issue when I made my decision that I’d prefer the UK to leave the EU). But I’ll ask the same question as I always do: if immigration was the deciding factor for many people, so what if it was?
//We had the UK's Human Rights Act and the European Convention on Human Rights in 2018 when just 299 came.//
In fact the number of irregular arrivals in 2018 was estimated to be around 14,000, with around half that number arriving by small boat:

//Neither legislation has changed in the last 3 years, so I have to assume it was the half hearted and useless management of the Home Secretary was the reason for the deterioration of the border force, similar to the UK's police force which is no longer fit for purpose.//
In order to support that you’d need to know how many attempts were made at illegal entry. It is doubtful whether the level of detection is any different now to the level seen in earlier years. But the number of attempts has risen considerably simply because, once here illegal migrants know they will not be removed. As well as that, in the past few years the chosen mode of travel has shifted away from stowing away in lorries (which was not particularly easy) to simply embarking from the French coast in an inflatable. It doesn’t matter how strong a border force the country has. If all it is going to do is to meet the rubber boats when they cross into UK waters so as to ensure their safe arrival, all that increasing the strength of the BF will do is increase the number of arrivals. It is frankly ludicrous that an organisation tasked with keeping the borders secure actually facilitates illegal arrivals.
//In fairness it needs to be properly planned, legally sound and properly implemented.//
What do you suggest is done (properly planned, legally sound and properly implemented) under the current overarching legislative framework, fatticus?
