First Moves, a 32-page magazine, has been launched specifically for the young urbanite readership that the Metro currently caters to.
A total of 300,000 copies will be distributed between now and Friday, half inserted into the Metro, with the other half distributed by hand by merchandisers at "key locations" across London.
A spokeswoman for the Metro said that it had not been decided how frequently the title would appear in future. However, the company said that the title would be the first in a number of launches using the Metro branding.
Metro managing director Linda Grant said: "As we move the Metro brand forward, and into new areas, it is exciting to launch the first in our new series of magazines.
"It is an incredibly hard time for those trying to get on the first step of the property ladder. We know that many of our loyal urbanite readers are in this first-time buyer category and I’m confident this launch issue of First Moves will help buyers through this tricky process and offer advertisers the opportunity to connect with this key audience."
The magazine will include features, advice and tips for Londoners buying their first home – from choosing a solicitor and making an offer right through to the move itself.
