Gowling WLG has jumped into first place in the most recent AIM rankings after gaining three clients, bringing its total to 56 AIM-listed clients.

The rankings, complied by finance data provider Adviser Rankings, also show that Pinsent Masons has equalled DLA Piper in its number of FTSE AIM 100 clients, making them joint first with seven clients each. The information is based on data from the third quarter, finishing 6 July 2016.

Pinsent Masons M&A partner Jon Harris said he had been concerned that the Brexit vote would damage Pinsents' ability to stay at the top of the FTSE AIM 100 table but in recent weeks his concerns had diminished.

He said: "What we are seeing is a continued strengthening here in the UK. However, while AIM is very important to us, so are all the markets such as Asia and Europe. We are starting to think more internationally."

Gowlings corporate finance partner Charles Bond also struck an optimistic note when asked about how the Brexit vote might affect his firm's position. He said the firm's focus on clients involved in the mining industry would likely allow it to weather any consequences well.

He said: "Generally, the commodities market has not been affected by Brexit because most of the mining is outside the EU, in places like Malawi and South America."

The data shows that other winners include Osborne Clarke (OC), which has shot into 11th place on the list of total AIM clients after it gained two clients during the quarter. OC also topped the FTSE AIM UK 50 client list, closely followed by Addleshaw Goddard and DLA Piper in joint second place.

On top of this, OC was first on the consumer goods client list and consumer services client list.

Other big changes include Olswang moving into eighth place in the FTSE AIM 100 client list, now having grown its client base to four, up from one.
