Does it get darker than astronomical twilight in London England on nights near the June solstice?
Wikipedia sez: "Astronomical twilight is defined to begin in the morning, and to end in the evening when the center of the Sun is geometrically 18 degrees below the horizon." London, England is at 51 degrees north latitude. At midnight in the June Solstice, the Sun is at a declination of 23.5 degrees (approximately), so the over-the-pole angular distance is (90-51) + (90-23.5) degrees, or 105 degrees. The horizon is 90 degrees, so the Sun is 15 degrees below the northern horizon at midnight on June 21. So, no, it won't meet the definition for "darker than astronomical twilight".

Does the sun go more than 18 degrees below the horizon at night in London England near the June Solstice?
At the June Solstice, the Sun is about 23.5 degrees north of the equator. London is at 51.5 degrees north latitude. So at midnight around the solstice, the Sun is (90-51.5) + (90-23.5) degrees north of London. So, the Sun is 105 degrees away from London. The northern horizon is 90 degrees, so the Sun is only 15 degrees below the northern horion.

Does astronomical twilight end near the summer solstice when observed from Greenwich England?
No. Around the Summer Solstice, "astronomical twilight" lasts all night for everywhere in England. The southernmost point in England is Lizard Point, in Cornwall, at 49 degrees 57 minutes North.(Call it 50 degrees even, to make the math easier.) Around the Summer Solstice on June 21, the Sun is at a declination of 23 degrees 26 minutes. (Let's round that off to 23.5 degrees.) At midnight, the Sun is at 23.5 degrees North over the Pacific Ocean. That means that from Lizard looking north at midnight, the Sun is (90-50) + (90-23.5) degrees = 40+ 66.5 degrees =106.5 degrees away. That means that the Sun is 106.5-90 degrees below the horizon. "Astronomical Twilight" is defined as the Sun being less than 18 degrees below the horizon. On June 21, the Sun is only 16.5 degrees below the horizon at Lizard, and less than that anywhere else in England. So around the Summer Solstice (about a week either side of it, actually) the Sun is never more than 18 degrees below the horizon from anywhere in England, Scotland or Ireland.
