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.
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".
No, there were no light pollution in London, England, it would not be pitch black at Summer Solstice because there is a full moon.================================Answer #2:At the time of the Summer Solstice, the sun's declination reaches roughly +23.5°.London's latitude is in the neighborhood of 51.5° North. That's still 15° southof the Arctic Circle, so the sun dips as much as 15° below London's horizon.That ought to be plenty to guarantee a very dark night.There's no connection between the Summer Solstice and the phases of the Moon.
This is the latitude and longitude of London, England.
