There are different categories of visa that you can apply for to visit the UK. The most common visa types granted are probably ones with 6 months validity and one-year validity. Travellers can enter the country, any number of times within the period of the visa validity.
Individuals who keep going back to the country for business or to visit children settled there are granted long-term visas for up to 10 years. Individuals can enter the country any number of times during the period the visa is valid but can stay in the country for no longer than 180 days, at a stretch. Such individuals do not have to reapply for a visa each time.
What people with long term visas do is, leave the country for a week or so, and enter again. Vijay Mallaya probably has a long-term visa to the UK since his businesses are spread in the country.
However, a long-term visa is generally not granted for the first visit.
