RUGBY chiefs are reported to be exploring the possibility of inviting London Welsh and London Scottish to join the Guinness Pro12.

According to a report in The Rugby Paper by Peter Jackson, informal talks have already taken place with both clubs.

“Discussions behind the scenes are still at a very informal stage,” The Rugby Paper quotes ‘a source’ as saying.

“There are some big obstacles to be overcome but it is worth finding a way round them because of the commercial advantages to all parties.

“The introduction of London Welsh and London Scottish to the Pro12 will open up the London market.

“It will tap into the Celtic diaspora in the Home Counties and increase the value of our competition.

“Will it happen? It’s got to happen, not next season but possibly after that.

“It might be less than 50-50 but we cannot survive on our current commercial income and having two London teams would give us a major boost.”

Kelvin Byron, London Welsh’s majority shareholder and principal backer told The Rugby Paper: “Playing in the Pro12 is an interesting idea. Let’s see what happens.”

Welsh are rock-bottom of the Premiership table with just one point having lost all 20 matches this season.

Head coach Rowland Phillips signed a new deal with the club last week as he prepares to lead them in the Championship next season.

Phillips took over the role in March, having initially joined the club as defence coach in November 2014.

"I'm excited about the challenge of guiding the club back to the Premiership and we have already begun planning for next season," Phillips said.

Meanwhile, the Pro12 also has to resolve outstanding issues with Treviso and Zebre.

The two Italian teams are said to owe the competition more than £1m and have reportedly been set a deadline believed to run out before the end of the month.
